I have a media server that used to work: 4 disks, EXT4, as a single LVM with 5 shares.
Working through other tutorials, when I execute the “lsblk” command this is what I see:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1.8T 0 disk
└─Fantasia-Fantasia 253:0 0 9.1T 0 lvm
sdb 8:16 0 1.8T 0 disk
└─Fantasia-Fantasia 253:0 0 9.1T 0 lvm
sdc 8:32 0 1.8T 0 disk
└─Fantasia-Fantasia 253:0 0 9.1T 0 lvm
sdd 8:48 0 3.7T 0 disk
└─Fantasia-Fantasia 253:0 0 9.1T 0 lvm
sde 8:64 1 14.9G 0 disk
├─sde1 8:65 1 14.2G 0 part /
├─sde2 8:66 1 1K 0 part
└─sde5 8:69 1 667M 0 part [SWAP]
sr0 11:0 1 1024M 0 rom
The boot drive is “sde” the rest of them are all full disks that are part of the LVM “Fantasia”.
I don’t see any files, but everything seems to be mounted, but I don’t know what it SHOULD look like for it to be correct, and if not correct, how can I go about fixing it.
This is from a media server that I’d LIKE to recover rather than have to rebuild from scratch, but at this point I don’t have a lot to lose, so if there are techniques I could use to try to, erm, I don’t know recover the lvm information from a superblock? Jargon? Is there a way to even determine what the problem is and if it’s something which can be fixed?
Tinkering with file systems is not for the faint hearted, I know, but my inability to even articulate, technically, makes even searching for possible answers challenging. It has been suggested that the “filesystem header is gone”. Ok, if that’s true, is there a way to confirm that or recover it? etc.
Kind of “crying out to the internet” here hoping someone can hear my plea… so thanks in advance…
