this is a linux redhat HP ml350 g4 machine. after using lvextend to extend the lvol, i tried to umount the fs so i could increase it. i got device is busy alert but i was not in the directory nor was anyone else on the system. i had to comment out the fs in /etc/fstab then reboot to umount the fs. i was then able to extend it and mount it. why did i get device is busy msg. thanks
Re: getting "device is busy" msg but no one is in fs
fuser -cu /filesystem_name
fuser -cuk /filesystem_name
should kill all processes on the filesystem.
More than likely your connection to the box will terminate.
Best solution is to boot the box.

Re: getting "device is busy" msg but no one is in fs
Maybe You simply had a running process there or something was mounted below that filesystem? Also possible would be a open file handle from rm'ing an open file. There's almost no other reason!
yesterday I stood at the edge. Today I'm one step ahead.
Re: getting "device is busy" msg but no one is in fs
. lsof may have shown some proc in the mount. not sure anymore. but it was one of the solutions provided as i agree that it really could be nothing else.
