It's much more likely to be a problem with your disks or filesystem than
with PostgreSQL.
"Invalid argument" is a standard system call error code translation for
the code -EINVAL .
You should check your kernel logs for error messages about your disks
and file systems. You should also run a file system check (fsck) on your
filesystems. If you have a RAID array, get it to do a
verification/scrubbing run too.
