I am not how I have managed this but I have corrupted two volumes on my instance “Newest_3_species”. Is there a backup of these that can be restored? It is hosted on Warwick.
The drives appear like this when i do “ls -tnh” from the home directory.
d????????? ? ? ? ? ? Extra_storage d????????? ? ? ? ? ? More_extra_storage
running “sudo e2fsck -nf /dev/sdc” gave me:
sudo: unable to resolve host newest-3-species e2fsck 1.42.13 (17-May-2015) ext2fs_check_if_mount: Input/output error while determining whether /dev/sdc is mounted. ext2fs_open2: Bad magic number in super-block e2fsck: Superblock invalid, trying backup blocks... e2fsck: Bad magic number in super-block while trying to open /dev/sdc The superblock could not be read or does not describe a valid ext2/ext3/ext4 filesystem. If the device is valid and it really contains an ext2/ext3/ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> or e2fsck -b 32768 <device>
When I try to do anything in that drive I get an “input/output” error!
Running dmesg says there is an I/O error and that error -5 is returned: for both sdb and sdc:
[1448154.372768] XFS (sdb): xfs_log_force: error -5 returned. [1448171.652655] XFS (sdc): xfs_log_force: error -5 returned.
This is really concerning and I hope there is a way to recover these drives!
