Osmo NZL Posted November 12, 2020 Share Posted November 12, 2020 Hey guys My Cache drive is coming up as Unmountable: No file system. I've read through the forums and tried the help section from... But when going through the steps I am able to save the info from the cache drive to folder /x but when copying from /x to a backup folder on disk 1 of the array using midnight commander a lot of the files comes up with an error of... "cannot read source file "etc etc etc" input/output error (5)" It just gives the options to skip, skip all, retry, abort but I feel I need ALL of the info from the cache in order to format it and copy everything back across in order to have my cache drive running again. I am all new to this stuff, any help would be appriciated. unraid-diagnostics-20201113-0437.zip Quote Link to comment
JorgeB Posted November 12, 2020 Share Posted November 12, 2020 Diags are after rebooting, what recovery option from the FAQ are you trying? Quote Link to comment
Osmo NZL Posted November 12, 2020 Author Share Posted November 12, 2020 I'm trying to copy all the files from the cache drive (a 120gig SSD, sdb) to the disk1 of the array so that I can format the cache drive and rebuild it using the files that I've made on /x (as per the faq forum link I posted). unraid-diagnostics-20201113-0650.zip Quote Link to comment
JorgeB Posted November 12, 2020 Share Posted November 12, 2020 You didn't answer my question but I assume you're using option 1 in the FAQ, i/o errors during copy suggest checksum errors or another hardware issue, try option 2 (btrfs restore). Quote Link to comment
Osmo NZL Posted November 12, 2020 Author Share Posted November 12, 2020 Oh sorry, yes I was trying option 1. Option 2 gives me the following error... ERROR: cannot map block logical 23644340224 length 2147483648: -2 Error copying data for /mnt/disk1/backup/system/libvirt/libvirt.img Error searching /mnt/disk1/backup/system/libvirt/libvirt.img Error searching /mnt/disk1/backup/system/libvirt/libvirt.img Quote Link to comment
JorgeB Posted November 12, 2020 Share Posted November 12, 2020 Use the option that skips errors. Quote Link to comment
Osmo NZL Posted November 12, 2020 Author Share Posted November 12, 2020 Ah yes sorry just read that bit (I'm trying to fix my server and get the kids ready for school at the same time - naughty dad lol)... Quote Link to comment
Osmo NZL Posted November 12, 2020 Author Share Posted November 12, 2020 OK sweet. It looks like it did it. looking at the files in the backup that it created it looks like all my dockers and VM is saved. Nice. The FAQ says... "If it works check that restored data is OK, then format the original btrfs device or pool and restore data." Just not sure about the restore data part. After I format the SSD do I just copy these files back over to it once its formatted? Quote Link to comment
