Jan 6 03:29:29 am postgres[30621]: [16-1] ERROR: could not create file
"base/21289/23519_fsm": Input/output error
Error writing to xlog not a fatal error too.
Why it's not a fatal error for server?
Server worked more then 4 days with broken FS.
As the result I lost server and backup for a last 4 days
Is it possible somehow to avoid it in future?
