Using FreeNAS 8.0
I first connected 4x2TB to the 4 SATA ports integrated on the motherboard.
A raidz array using these four drives seemed to be working well.
I then connected another 2TB disk and a 60GB SSD to a 2 port PCI-e SATA card.
When booting it seems like these two new disks are detected first, which
resulted in two of the old 2TB disks being available for creating a new volume. :-O
The BIOS does not seem to have any support for rearranging disk order...
I'm not familiar with FreeBSD disk enumeration... ;)
Question:
Is there a way to lock the raidz members to serial number (or similar) rather than
the order the disks were detected? Or have I misunderstood what is going on?
(Tried to post under "hardware" as well since it is not clear where to find the solution...
But someone didn't like duplicate posts... ) :(
--- Update --------------
Is no one here even A BIT CONCERNED about this behavior?
From a quick scan of the web, it seems like FreeBSD-people recommend labeling the drives to prevent confusion about which disk is which when a disk dies.
But from what I've also read, people seem to be convinced that zfs can handle moving disks by looking at the meta-data stored on them. If that is true, then it is the FreeNAS GUI that is confused about what disks are available for creating new volumes...
Is anyone sitting on the truth? Anyone?
