Hi, am running pihole in one of lxc cont. but after some time(maybe a day?) there is no response from pihole web interface.
SSD is mounted, but when trying to attach error message is received:
bash: /etc/bash.bashrc: Input/output error
What could be the the issue here?
Could be faulty disk / filesystem.
Check dmesg if you see anything relevant, and or /var/log/messages
Hi, read somewhere that mounting drive with clear_cache option can resolve those issue but today experienced similar error:
root@turris:~# lxc-attach -n vrata
lxc-attach: vrata: parse.c: lxc_file_for_each_line_mmap: 107 I/O error - Failed to sendfile “/srv/lxc/vrata/config”
Failed to load config for vrata

Also when loading PiHole GUI status was “UNKNOWN” before gui couldn’t even load so I presume that option clear_cache did at least something.

This shows write and read errors on sda. Read errors are increasing.
Try to run a btrfs scrub on that device, make sure the device is correctly connected.
When btrfs encountered errors it usually switches to read only mode so that is probably why lxc acts weird.
