The controller of my SSD (Samsung 980 Pro…) died so I have to rebuild my setup from backups. The first step is to install PVE and on top of that PBS and update everything, then do my LUKS setup on my external RAID and recover /etc/pve from a backup.
The original setup is:
Hardware Internal Samsung 980 Pro NVMe SSD (now dead) Mercury Elite Pro Dual Mini hardware RAID1
Encryption at rest SSD Password luks-fa1483bd-f599-4dcf-9732-c09069472150
PV /dev/nvme0n1p3 /dev/mapper/luks-fa1483bd-f599-4dcf-9732-c09069472150
VG pve rna-mepdm-1
LV-thin YES NO
LV (size) vm-100-disk-0 (32GB) vm-100-disk-0 (801GB)
Used as CLIENT boot disk CLIENT: /mnt/ServerData (300GB) ext4 UUID:109bd659-811d-442e-9539-ebf3673d9ad3

The server data (of the single VM I am currently using) lives on the RAID, and gets backed up to a LV on the internal SSD (as well as to the cloud). I have not lost server data, I lost the internal backup of server data, but I still have one external restic backup of server data on B2.
The VM itself lives on the internal SSD and gets backed up with PBS to the RAID. I lost that VM, but I have a PBS backup on the RAID.
I had:
Code:
root@pve:~# vgs -o +lv_size,lv_name
VG #PV #LV #SN Attr VSize VFree LSize LV
pve 1 6 0 wz–n- <931.01g 15.99g <794.79g data
pve 1 6 0 wz–n- <931.01g 15.99g 8.00g swap
pve 1 6 0 wz–n- <931.01g 15.99g 96.00g root
pve 1 6 0 wz–n- <931.01g 15.99g 32.00g vm-100-disk-0
pve 1 6 0 wz–n- <931.01g 15.99g 32.00g vm-100-disk-1
pve 1 6 0 wz–n- <931.01g 15.99g 500.00g vm-100-disk-2
(and the RAID entries)
After installing PVE and PBS and unlocking the external RAID I have
Code:

I lost the internal SSD, so I lost my VM (which I should be able to restore from the PBS backup), the docker cache of the VM, and the restic backup of server data (of which I still have external backups).
Now, the bad news is that I probably have lost a .tar.gz of /etc on the pve host, and the one I still have might be from PVE 8, so before I upgraded to PVE 9 a few months ago (I hope that upgrade is not what finally killed my SSD controller for some reason, but I don’t expect it).
Basically, I need to recreate the LV thin VG and the LVs, but I recall that doing that from the command line did not work years ago when I first set it up (2022, PVE 7). What is my best way forward at this point?
Stupidly unplugged my raid 5 configured thunderbay without ejecting and now it’s showing as disk structure corrupted and raw. Can anyone here recommend a service center/technician in Houston ? Not worried about the cost, just want the best option as I need my work files back.
Would also appreciate any insight into how screwed I might or might not be. Most of the files are .3FR raw files at ~200mb, if that matters.
Thanks in advance
I have a Flatbed server that has 4 hard drives installed in a raid configuration. Now the issue I am having is to try and recover data on one of the raid hard drives.
Now I was told that if one hard drive becomes non-responsive (freezing), the entire thing is buggered.
From the community, is there another way to clone that bad hard drive and get the system to boot up or will it continue to give me problems no matter what I attempt to do???
(Update) Tried a paid iPhone data recovery tool and it actually worked! Got most of my missing photos and videos back after scanning my iPhone. Definitely a lifesaver finally.
I’d suggest trying a trusted recovery software. Most of them show a preview before you actually recover anything.
But not always. The data still exists internally until overwritten. Recovery tools just access that leftover data.
Really? I thought once deleted, it’s gone for good.
Edit: I just now got to know that there are some data recovery tools that scan your iPhone directly and try to pull deleted files. I’ve seen people recover photos, messages, and even WhatsApp chats that way. I am going to give them a try.
No backup on iTunes either 😓 I mostly relied on iCloud, which was already full.
In that case, recovery might still be possible if the data hasn’t been overwritten yet. Did you try restoring from iTunes backup?
I don’t think so. My iCloud storage was full, so backup probably didn’t happen.
That’s frustrating. Sometimes updates can mess with local data. Were those photos backed up on iCloud?
Hey guys, I updated my iPhone yesterday and noticed that a bunch of my photos are missing. Checked Recently Deleted too, but they’re not there. Any idea if they can be recovered?
Thank you so much for suggesting Stellar Data Recovery—it actually worked! I was honestly not expecting much, but I gave it a try after checking the basic things first. The scan took some time, but it was able to find most of my missing files, including some really important documents and photos. I managed to recover almost everything, which was a huge relief. I was pretty stressed thinking all my data was gone, so this really helped a lot.
Really appreciate the suggestion
I have a Dell XPS laptop circa 2022, running Windows 11. It’s been running very well for 4 years. Last week I tried to install Windows Subsystem for Linux (WSL) using the Powershell command wsl — install. The installation said it was successful, and upon reboot, Windows would not load. I get the message “Your device has run into a problem and couldn’t be repaired. Click or press enter to see other recovery options.”
I took it to a computer shop. He tried several different methods to recover, none of which worked. He ultimately had to re install windows. He did test all hardware and ruled out any issue with the hardware.
Anyway; I had basically a brand new computer at that point, and had to start re installing my software. I reinstalled Dropbox with no issue and recovered my files. I re installed Microsoft office, and WireGuard. Then I got to reinstalling Adobe Creative Suite. The installation said it was successful. Upon reboot, I got the “your device has run into a problem and couldn’t be repaired” again. It references a log file on the C drive, which of course I can’t access because I can’t even get to Windows.
What is likely happening? How do I stop this?
