andreidelait Posted November 26, 2020 Share Posted November 26, 2020 I don't know what to blaim yet. I have to get the cache SSD out of the server and try to find out what's wrong with it. As I mentioned it happened before and the SSD looked fine at the time. Any help is really appreciated. tower-diagnostics-20201126-1246.zip Quote Link to comment
JorgeB Posted November 26, 2020 Share Posted November 26, 2020 It's filesystem corruption, can't see an apparent reason, and if it's not the first time it might indicate a hardware issue, good idea to run memtest. Quote Link to comment

Thank you for the quick reply. If I remember corectly the Unraid USB has a built in memtest? Or should I prepare a memtestx86 for this? Quote Link to comment
JorgeB Posted November 26, 2020 Share Posted November 26, 2020 You can use the one built in, it doesn't work with UEFI boot though, only legacy/CSM. Quote Link to comment
itimpi Posted November 26, 2020 Share Posted November 26, 2020 If you want a UEFI version of memtest you need to download it off the memtest site and use it to create a bootable USB drive. Quote Link to comment
andreidelait Posted November 26, 2020 Author Share Posted November 26, 2020 Thank you for the advice again. Indeed I have a bad stick of RAM and you pointed me in the right direction. Should I try to recover the cache drive somehow or is better to recover what I can and format it? Any BTRFS commands I should try? I have a few unassigned HDDs using BTRFS. Should I be worried about that data too? Quote Link to comment
JorgeB Posted November 27, 2020 Share Posted November 27, 2020 Best bet is to re-format, there are some recovery options here if you can't just copy the data. 10 hours ago, andreidelait said: I have a few unassigned HDDs using BTRFS.

Btrfs is very susceptible to bad RAM, but any issue is also usually pretty evident, you can run a file system check (without repair enable) to make sure all is well. Quote Link to comment
andreidelait Posted November 27, 2020 Author Share Posted November 27, 2020 I got burned two times with this, so I guess I'll convert everything to XFS as soon as I can. For some reason I tought I can only use BTRFS for cache drive. Quote Link to comment

That is only true if you have more than one drive in the cache (pool). With a single drive it can be any supported file system. Quote Link to comment
