I'm not sure what level of jfs is in that kernel, or whether a patch might help. I can look into it more tomorrow. > Every so often I get a hung mailbox file that ends up with many > threads stuck on it.

You get hanging threads when something crashes while it's holding a lock on the object. > sync appears to work, returns a prompt afterwards. Odd, sync often hangs in this situation. > Is there something in the utils that might save this file? It may be possible with jfs_debugfs, but you'd have to be somewhat of a jfs expert. > Rebooting seems to be the only way to unstick, and that deletes the > hung .mbox file. You could edit /etc/fstab so that fsck does not run against that partition when you reboot. (Change the last column in the entry to zero.) Then mount it read-only (mount -oro) and try to copy the file. This may still fail, but it may be worth a try. If you recover the file, then you can umount it and run fsck. > --thanks -- David Kleikamp IBM Linux Technology Center ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
