The screen shots under Online RAID Level Migration unfortunately aren't consistant. But the exact number of disks used really shouldn't matter, the principle should be the same.grocovid wrote:Yes but, the same page describes a procedure to go from Single * 1 to Raid 5 * 4 by adding not 3 but 4 disks...
That's the main idea with all migrations....and I can't find a procedure for online raid level migration if I want to original single disk to still be used as part of the resulting raid 5 array.
Yes it is (or at least should be) possible.Is that indeed possible?
I don't know why the migrations described here have failed but it looks as if adam3948 had a power failure during migration. SHoffEsq initially had disk failure (that caused a degraded array) and if he wasn't successful in deleting all data from all the disks he had previously failed to migrate, that would explain his problems. These are all things that normally shouldn't happen and they may of course affect a migration in a negative way.Isn't that the reason why the previous posters in this thread failed to do so?
I strongly recommend you don't do that!grocovid wrote:Can I leave read-only services on (like my NFS sharing, which is configured to be read only)?
Web administration can be up but personally I like to play it safe and did only logon briefly to check the status. Maybe the reason my migrations have worked is I'm being overly cautious?Do I have to turn off http(s) as well (for NAS administration) and only leave telnet/ssh on?
