@Kees, Can you please do the following: 1) echo 1 >/proc/sys/kernel/lock_stat fire the unmount command. 2) less /proc/lock_stat If you could attach the output of the previous command then we could check if there is some lock contention occurring.
You could then disable lock_stat as follows: 3) echo 0 >/proc/sys/kernel/lock_stat 4) echo 0 > /proc/lock_stat Thanks! -- very slow filesystem I/O https://bugs.launchpad.net/bugs/543617 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
