JorgeB Posted August 3, 2020 Share Posted August 3, 2020 Syslog rotated so can't see start of the problem, see here to reset errors and to monitor for more in the future. Quote Link to comment

JorgeB Posted August 3, 2020 Share Posted August 3, 2020 Current cache is sdg, you need to adjust the mount point, what was sdi being used for? It's not on current diags, suggesting that it might have dropped or been removed since. Quote Link to comment

I had an ssd (formerly sdg - sandisk) that crashed. 1) shutdown system 2) removed bad ssd 3) added new ssd 4) brought up system 5) stopped array 6) changed cache to the new samsung ssd Did I do something wrong here?

JorgeB Posted August 3, 2020 Share Posted August 3, 2020 Something is wrong but like mentioned can't see the beginning of the problem, reboot and post new diags if there are still errors. Quote Link to comment

Also what does this mean? Total to scrub is bad or just a metric? Ran brtfs scrub previously; came back with no errors. Edited August 3, 2020 by repomanz Quote Link to comment

Look OK if it was a a replacement without copying data from the old device. 22 minutes ago, repomanz said: Total to scrub is bad or just a metric? That refers to the used size, not device capacity.

My previous SSD started reporting reported uncorrected errors, within 6 hours the drive was completely dead. Do you have any tips on how to properly backup the VM lib and docker img files (basically containers and vm information)? I'm already using the plugin that backs up appdata (which i restored from).

JorgeB Posted August 3, 2020 Share Posted August 3, 2020 No need to backup the docker image, I believe that CA appdata backup already has the option to backup libvirt. Quote Link to comment
repomanz Posted August 3, 2020 Author Share Posted August 3, 2020 totally missed that previously. Updated now think we're all good here. 1 Quote Link to comment
