I got suggested (Synology AI) to make a full hyper backup, but this requires a C@ subscription or a second NAS…
Starting the docker containers causes a file checksum mismatch on a docker container file, and Volume1 becoming readonly.
Preventing to start of the docker containers, prevents triggering the file mismatch, and so keeping a rw RW Volume1
During backup I have some multiple other file checksum mismatches on file which did not trigger a Volume1 becoming readonly (and I have some older backups)
Volume1 is hybrid raid with 1 drive fault tolerance btrfs 5.2 TB 3.3 TB free. And is scrubbed.
So 2 slots in my 4 bay system
3rd slot is empty, and 4th slot is for video surveillance recording ext4-fs.
Surveillance package stopped for now.
Both Volumes and all 3 drives reports Healthy.
Volume1 has 2 WD60EFRX-68L0BN1 6TB
Having 2 new HDDs:
Seagate IronWolf ST6000VN006 6TB
How to replace the Volume1 HDDs?
What is the best way?
1)Take them both out and replace by new? But what about user shares etc….
Can I put back the old volume! as disc3&4 and copy the data to the new Volume?
2)Turn off, Replace one, turn on, rebuild, turn off, replace the other, turn on, rebuild
3)Add a hot spare in the free slot 3, …
replace first and rebuild?
make second (old) hot spare?
4)
…???
Hi guys – I’ve run a NAS system for a few months with in a Jonsbo N3 case, CWWK Q670-NAS 8 bay motherboard, Intel i9- 14900K CPU and 48Gb of Crucial DDR5 memory.
It started giving me some errors on one of the CPU cores so I started to troubleshoot. I rebooted to Memtest and ran that for a while with no errors.
Then I booted to a Linux bistro so I could run OCCT which also ran ok with no errors – I was running a test using Prime95 when the system just shutdown immediately. Since then I have replaced the PSU, CPU and motherboard and nothing works. The system simple clicks once, the PSU, CPU and system fans all spin up for a second and then stop and nothing else happens.
I’m at a complete loss as to what to try next.
Please can someone give me a pointer or two….
Crashed volume and one bad sector are observed in the Storage Manager for DS212, WD60EFZX, SHR/EXT4 (no data protection). At the same time diagnostic software (WD Kitfox) shows no errors or remapped sectors (at least after one full surface test pass). Is it possible to fix the volume without recreating it? Thanks.
Hi – I am in a bit of a sticky situation and am hoping someone can help me out. I have a 4 bay DS418Play NAS with all 4 bays in use. I had set it up as SHR1 but after one of my drives crashed, I replaced with a new one. However soon after that, the new drive crashed as well. I figured my NAS is falling apart and i need to buy a new one, so i shut the NAS down while waiting to buy a new NAS. 2 days later, i needed access to a file urgently on my NAS so i turned it on and downloaded my file, but my NAS suddenly restarted and after restart I had another drive showing up as crashed. So now I have 2 drives crashed out of 4… and after the restart when I tried to access my data in the NAS, i could not see any data in the NAS đ. But i feel certain that the data is not lost in the drives and it is the NAS which has caused the drives to crash. But i am not sure how to recover my data safely. I have not turned on my NAS since that day yet. How can i recover my data or rebuild the NAS (or transfer to a new NAS) with minimal risk of loss of data? I would like to avoid giving my drives to someone else (e.g. a professional) if possible for privacy reasons.
Hi, was wondering if the group here can help guide me in the right direction:
1) I have 75-100 TB’s of data than I need to keep online or near-line.
2) These data sets do not change and seldom deleted
3) Currently, we are storing them in a large RAID 6 array, and have a duplicate array for backup
4) My worry is both array’s will fail leading to data loss
Is there a way to access a LTO-8 library like it’s a hard drive? We don’t need super high speed access since we can copy the data sets as we use them to local harddrives.
I don’t know too much about LTO tape libraries, but was thinking this will be a good use of tape storage.
Thanks!
i need to improve and streamline how our projects get archived and backed up.
I need some advice regarding software solutions for running backups to an LTO drive.
Our two Flame suites have local storage on each.
Currently we have two Synology Raids (one onsite, one offsite) that hold the backups for disaster recovery purposes. These are big, and getting bigger all the time as (until now) we have stored everything we have ever done. Not deleted anything and still have rushes and all files for projects going back 16 years!
The graphics dept also uses this system for a working drive and backup.
The Synology use the Syncovery software to run the backups.
I used to use LTO 5 tape library, but the amount of tapes required to alternate on a weekly basis was getting to much to handle, and I was convinced by our IT dept to go the Synology route. I now realise that was not planned out as thoroughly as it should.
Now I want to evolve to a hybrid, where the Synology raids are used for Disaster recovery purposes, ie, backing up the daily projects and work files, and to look into getting a new LTO drive and using tape for long term storage.
The idea being that I can set up the backup system to no longer store everything forever, but to keep a 30day snapshot rota and a backup type that retains a duplicate of the current drives. Hopefully this will then delete any files no longer on the local drives and help to keep the data load to a more manageable size.
For software I have used Retrospect in the past but found it a little flaky once the backups got too large. Synology is not easy to understand, and after being setup by the install engineer, I have been stumped by some of its settings. Documentation for it seems non existent!
The main question is âŠWhat software are you using to run your backups?
Has anyone got alternate strategies for backups that might be more workable?
Thanks for any insight you might be able to offerâŠ
Thatâs the right mindset.
One last tip: donât restore backups or sync anything before scanning. Sync can overwrite local remnants.
Good luck, and yeah, please update the thread. These situations help others avoid the same mistake.
Appreciate the honesty here. I wasnât expecting miracles, just hoping itâs not totally gone.
Iâll try a PC-based scan later today and see what shows up. Even getting back some of the older photos would be a relief.
Iâll update once I try it.
Just to set expectations realistically: no recovery method brings back 100% once app data is cleared.
But if:
phone wasnât factory reset
storage wasnât encrypted and wiped
device is still accessible
then scanning internal storage from a PC-based Android recovery tool is usually the best shot.
Success depends heavily on how quickly you act.
Yes, thatâs actually very normal.
Older files sit in older storage blocks, which are more likely to be marked as free and reused first. Newer files may still be intact because they were written later.
When I went through this, I only recovered photos from about 6 months back, nothing recent. Partial recovery is common in these cases.
That makes sense. I almost installed a recovery app from Play Store but held off.
One thing Iâm confused about: some newer photos are still there, but older ones are gone. Is that normal?
Adding to what Silas said.
Donât try random âfixesâ or cleaner apps now. Iâve seen people make it worse by trying to optimize storage again.
If youâre going to attempt recovery, do it from a computer. Installing recovery apps directly on the phone writes data to the same storage youâre trying to recover from.
Correct. Clearing app data removes the appâs internal storage footprint.
WhatsApp stores media in specific folders. When you cleared data, the app removed references and likely deleted associated folders.
Thatâs logical deletion, not encryption or hardware damage. Recovery depends on whether those storage blocks were reused.
Important distinction: reinstalling WhatsApp doesnât bring that media back unless backup had it.
Thanks for replying, both of you.
Iâve stopped using the phone except to read this thread. No new apps, no downloads. Iâm honestly kicking myself because I didnât even realize âclear dataâ would wipe files too.
So this isnât just a WhatsApp issue, itâs storage-level deletion?
I am on Fedora Linux, and I was organising files to move to optical media. This is a BTRFS RAID 1 filesystem with FDE, which is shared via NFS. The permissions for this area are nobody:nobody.
I had the NFS share mounted on my laptop and was in admin mode within Nautilus (Fedora Workstation), and wanted to rename the folders, which has several files within them. After renaming (e.g. 25G-BD1 to BDR1) when I went to look at the folder, it was empty, much to my shock.
I am not sure why this happened exactly, but I can only think that the rename is essentially a move execution for the folder, and the files did not follow, maybe due to the permissions. Again, this confuses me – I was performing these process as “admin” which I suppose is just superuser and not actually root.
I later found out that doing such things over NFS within Nautilus isn’t a good idea, with permissions set as they are on the server – probably for this reason.
So I unmounted the NFS from the laptop, unmounted the disks from the server to stop as much activity as I could, and pray the CoW holds true.
As I thought about what my options were, I first looked at using testdisk but it was advised not to, and look at using BTRFS tools to recover, but I couldn’t remove/delete one mirror disk which I needed as a lifeboat to store and image of the remaining disk. BTRFS tools would not permit a removal of one half of a RAID 1 array. And I could not delete either as it would migrate back to the remaining disk, thereby causing rewrites.
So I was stuck. I needed another solution. Then I found about Hetman RAID Recovery. So I tried it out and it found the folders (and files) on the disk.
Before I went to consider a licence, I then stumbled on this reddit and realised not only did I miss out on a free licence giveaway a month or two ago, but you apparently are offering a free licence for The Partition Recovery – which as I understand it will do the job for a a single target disk from a RAID 1, and that the RAID Recovery is for more complex RAID arrays.
Needless to say, I have learnt a lesson here. I laugh at the irony that I lost my backups that I wanted to backup further (to cold storage).
I would greatly appreciate a key to restore my files. I luckily have a 1TB SDD free to restore this data to, before moving them back onto the array.
I won’t be doing what I did again, I thought it was a convenience to do things remotely but now I realise that with sensitive data I should really be on site at the server.
Thank you!
