Changed Order of Disks ! Now All Raids are "broken"

[gigicarlo]

Hi
I am very new - and running into some problems.

I have 5 disks in my raid (very new) and just copied a lot of data on it.
Then on disk was reported to not work - so i took them out and back in - and changed the order ?
Is that a problem ? I thought they are hot swappable and the order does not matter.

Now it sais 2 main volumes are "unloaded"

But on the Disk-Level everything seems to be ok.
I thought "RAID" is a bit more intelligent then this ... i tried to restore .. but nothing seems to work.

Any Ideas ?

yeah .. you cannot change the drive order when swapping disks hot, you busted your raid

if you want to change the order, do it cold. If you want to change a drive that is faulty do it hot (you can cannot exceed your parity count while rebuild is going on, otherwise your raid would fail)

RAID5 = one drive can be exchanged at a time (until rebuild is done)
RAID6 = two drives can be exchanged at a time (until rebuild is done)

Posting your NAS model and the firmware version is also a good idea when posting about issues. May or may not be related, but always a good thing to do.

Yeah, with a ZFS model (QuTS), rebuild of swapped drives is by far faster than on ext/mdadm in QTS devices, probably not as fast that a quick swap is possible, but not a full resync
