No matter what's going on, what do you prefer in case say - double disk failure from one mirror on 48 disk systems? losing completely data of 1/24 of users (and then restoring that amount from backups), or losing randomly chosen 1/24 of files from whole system? answer yourself. With UFS of course i would have single disk fsck time - less than a hour. which CAN be done out of work hours with soft updates. i normally turn off automatic fsck for large data filesystems, and if crash happened i run it after/before work hours.
