[comp.os.vms] Analyze/Disk/Repair -- Live?

SIBLOCK@MCMASTER.BITNET.UUCP (04/13/87)

        Many people have mentioned that they do $Analyze/Disk/Repair s
quite often.  Can this be done on a 'live' system?  I realize the
volume is write-locked as repairs are being made, but for how long
per repair operation?   It would be beneficial to to repairs more
often, but not if the system must be made unavailable to the
userbase.

I have done analyze/disk/repair on live filesystems several times and
have not had any problems. I generally use /confirm, just because to be
careful. This takes about 15 minutes for the system disk, an RP07, and
ten minutes for each user disk (RA81). The time presumably varies with the
number of files. One nice feature is that batch jobs in progress are only
held up and not aborted when the disk is write-locked.
