Roger, et al -- ...and then Roger Heflin said... % % The re-add will only work if the array has bitmaps. For quick disk Ahhhhh... Good point. It didn't really take 9 hours; a few minutes later it was up to 60+ hours, and then it dropped to a couple of hours and was done the next time I looked. I also forced the other array using just the last two drives and saw everything happy, so I then added the "first" drive and now it's all happy as well. Woo hoo. % hiccups the re-add is nice because instead of 9 hours, often it % finishes in only a few minutes assuming the disk has not been out of % the array for long. I love the idea. I've been reading up, and in addition to questions of what size bitmap I need for my sizes diskfarm:~ # df -kh /mnt/4Traid5md/ /mnt/750Graid5md/ Filesystem Size Used Avail Use% Mounted on /dev/md0p1 11T 11T 309G 98% /mnt/4Traid5md /dev/md127p1 1.4T 1.4T 14G 100% /mnt/750Graid5md and how to tell it (or *if* I tell it; that still isn't clear) there's also the question of whether or not xfs diskfarm:~ # grep /mnt/ssd /etc/fstab LABEL=diskfarm-ssd /mnt/ssd xfs defaults 0 0 will work for my bitmap files target, since all I see is that it must be an ext2 or ext3 (not ext4? old news?) device. Anyway, thanks again for the sanity checks and pointers. It's good to be whole again :-) I look forward to the day when I can dig into growing to more larger disks and have to contemplate reshaping from RAID5 to RAID6 :-) HAND :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
