my home server’s main SSD runs BTRFS. there was recently a power outage and my system is no longer able to function at all because of it.
i have a debian live session on a USB device i can boot, which is how i got these logs. this is using Linux 4.19.
i can read most of the files on this SSD, but there are some that cause errors when i try to read them. it so happens that at least one of these error-causing files is very important and i would like to avoid losing it by any means necessary.
i have already been ridiculed by my peers for not having a backup ready-to-go. lesson definitely learned. a backup script will be my first priority if/when i get this system back up and running.
my sincerest apologies, but i have no way to properly get a textual copy of my dmesg, the best i can do is upload pictures i have taken with my phone.
it correctly detects the partition table, but the FAT32 bootloader partition and the main BTRFS partition both show up as “MS DATA”. the swap partition is detected correctly.
UPDATE: i have used “btrfs restore” to create a copy of every file on the corrupted filesystem. including the ones i had trouble reading.
im not certain every file was copied correctly, but i have no choice but to assume they were. these copies are on my mass storage array.
unsure what to do now, still have a corrupted BTRFS tree on the SSD.
