in the end i had no choise but to reboot the server. btw, i tried once to mount -t cifs, and it took 5 minutes to hang the server so i was back to smb
anyway, i rebooted the windows machine without umounting the smb share many times , and it was no problem, the mount continued to work after the windows was up again. i am using linux since about 1994, and the umount problem was always relevant. then it was nfs, now it is smb (and probably nfs too) just can't figure out how a stable and mature system like linux, still have problems like a process that can't be killed even with -9, and that the only solution is to reboot we used to make fun of windows that had to be rebooted for anything, and that linux could do anything without a reboot. erez.

actually, that is the exact reason why i do not recommend my customers to use smb mounts on their servers (and especially not on production). mouting SMB shares on linux is not very stable, but the real problems begins when the SMB server goes down. then your mount will be hanged, and it will degrade system performance as well. (on some occasions programs tend to do stat on all the mount points, and when it gets to the hanged smb mount... you get the picture). anyhow, i believe that it is a new feature in 2.6, you can mount smb shares using '-t cifs' (instead of '-t smbfs') and that is considered a bit more stable. - Noam On 10/26/06, Erez D <[EMAIL PROTECTED]> wrote: > hi > > i have a linux server with a lot of people working on it, so i can not reboot it > > i need unmounting a locked SMB mount on it. > > i can not umount as it is busy > i can not kill the processes acessing it as they are in the 'D' state and are not killed even by kill -9 > > using mount to remount with soft and intr, just locks the mount command > > > umount -f does not do anything. > > system: centos-4 (rhel-4) linux-2.6.9 > > > any idea ? > > erez. >
