Hello everybody!
I'm just wondering, I had gmirror with two disks:
Master: ad0 <ST3160815AS/4.AAB> Serial ATA II
Master: ad2 <ST3160815AS/4.AAB> Serial ATA II
unfortunately ad0 failed today, leaving me with degraded array and ad0
offline.
I did
# gmirror forget gm0, then shutdown, ad0 was replaced with:
ad0: 152626MB <Seagate ST3160815AS 3.AAD> at ata0-master SATA300
with different firmware I think.
Then gmirror insert gm0 /dev/ad0
(...)
Jul 31 09:55:46 julia kernel: GEOM_MIRROR: Device gm0: rebuilding provider
ad0 finished.
Jul 31 09:55:46 julia kernel: GEOM_MIRROR: Device gm0: provider ad0
activated.
But the disk is a little bit smaller:
1. Name: mirror/gm0
Mediasize: 160040803328 (149G)
Sectorsize: 512
Mode: r5w5e6
Consumers:
1. Name: ad2
Mediasize: 160041885696 (149G)
Sectorsize: 512
Mode: r1w1e1
State: ACTIVE
Priority: 0
Flags: DIRTY
GenID: 1
SyncID: 1
ID: 3791030614
2. Name: ad0
Mediasize: 160040803840 (149G)
Sectorsize: 512
Mode: r1w1e1
State: ACTIVE
Priority: 0
Flags: DIRTY
GenID: 1
SyncID: 1
ID: 2477089776
# gmirror status
Name Status Components
mirror/gm0 COMPLETE ad2
ad0
so, it looks fine.
Can I expect any problems now because of different sizes? Any problems when
RAID will be almost full?
I mean - should I make the RAID once again with exactly the same drives, or
can I leave it as it is right now?
Thanks in advance!
