Pool SYS had been deactivated due to system date error 20012 (beasttree.c[504]). I rebuilt pool SYS and reactivated it, then rebooted. Server booted normally, and users logged in.

Some users reported that files (stored on sys:) from yesterday were missing. Many more files (email) were found to be missing and old messages that had been moved to trash were back in the inbox. These email files are stored on a volume in pool1.

Can a rebuild of pool sys affect what is in pool1?
