Hi Bill, One way to do this is to switch the server to admin mode. I think you can do that using pvfs2-set-mode in src/apps/admin. After that the server won't take regular requests I think.. I don't know if the fsck app already does that..You will of course need to switch the mode back after the fsck finishes... It has been a while since I looked at that code.. so I could be wrong.. :)
It would be best if you ask all users to kill their jobs before running fsck.. Online fsck is probably going to cause a lot of grief if users are actively using the volume... thanks, Murali On 8/31/07, Bill Wichser <[EMAIL PROTECTED]> wrote: > We'd finally like to run an fsck to try and clean up our pvfs2 > filesystem (see my previous post about kernel crashes) but are concerned > about users' jobs still accessing the filesystem while we are running > these checks. > > From the kernel interface, this is easy, we simply disable the kernel > module.
