Caller > 0x8718e102 This is probably a result of a write cache which isn't properly flushed during use prior to unplug (i.e. barriers; no idea what usb keys have for write caches etc, but btree errors wouldn't be unheard of due to lost/reordered writes due to write cache failure) As to your other question, Michael is right, filesystems don't call out to userspace repair tools when they encounter an error like this. You could make xfs_repair run prior to mount, but I'd focus more on why you're getting a corrupted filesystem in the first place. -Eric > Thanks, > Mike > > > ------------------------------------------------------------------------ > > _______________________________________________ > xfs mailing list > xfs@xxxxxxxxxxx > http://oss.sgi.com/mailman/listinfo/xfs _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
