Re: xfsdump INTERRUPT issue

[Jeffrey <grndlvl@xxxxxxxxx>]

Ok, I tried running the command. Here's my output:

# xfs_repair -n -r /dev/sda2 /dev/sda3
# Phase 1 - find and verify superblock...
# bad primary superblock - bad magic number 111
#
# attempting to find secondary superblock...
# ................

and the dots are still just going after about 15 min.

What should I do?

Best,
J.
