I have a Unifi NVR running on Ubuntu Server 16.04.5 LTS (Xenial) that runs for about a day before falling over. When I check the console I see pages of error text like this:
[136429.061821] EXT4-fs (dm-0): previous I/O error to superblock detected
[136429.065607] Buffer I/O error on dev dm-0, logical block 0, lost sync page write
[136429.068814] Core dump to |/usr/share/apport/apport 7415 7 0 1 7415 pipe failed
[136462.996124] systemd-journald[434]: Failed to send WATCHDOG=1 notification message: Transport endpoint is not connected
[136489.073364] EXT4-fs error (device dm-0): __ext4_get_inode_loc:4116: inode #1314111: block 524311123: comm kworker/u128:3: unable to read itable block

dm-0 is not a valid volume, so I assume it's some sort of cache. How do we figure out what's breaking it? Sorry, very new to Linux.
Thanks,

In the end it was far quicker to create a new VM, import the video data and NVR configuration, rather than figure this out.
