I have an ext3 filesystem on /dev/sdb1. I want to reconfigure it to use a journal on /dev/sda1, as the SCSI drives in question are old ones which are slow to seek, and I think it should improve performance.
So, I create an external journal on /dev/sda1 using mke2fs -O has_journal /dev/sda1 -J size=100 and attempt to attach it to /dev/sdb1 using tune2fs /dev/sdb1 -J device=/dev/sda1 which gives the error "The device already has a journal". The information in man tune2fs (a) did not lead me to expect this error and (b) doesn't say anything about how I might overcome it. Can it be overcome? Or have I totally misunderstood this man page and am within millimetres of nuking my filesystem? Pigeon -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
