Thanks. You're perfectly right, I should have done that.

Well, probably because I thought that zfs would simply handle the
situation. I just wanted to replace drive A with drive B, so this was
quite straight-forward for me.

Yes. The drives did not appear automatically (verified with atacontrol
list). Then I first tried reinit ata9, but that did not work out, so I did
a detach/attach for ata9, then the drive was there (with list and also
the device node appeared).

Of course (dmesg is not there anymore, I use pciconf -vl and
atacontrol instead):

The first six drives (up to ad14) are connected onboard (Supermicro dual
opteron board with mcp55):
atap...@pci0:0:5:0: class=0x010485 card=0x161115d9 chip=0x037f10de
rev=0xa3 hdr=0x00 vendor = 'Nvidia Corp'
device = 'MCP55 SATA/RAID Controller (MCP55S)'
class = mass storage
subclass = RAID
atap...@pci0:0:5:1: class=0x010485 card=0x161115d9 chip=0x037f10de
rev=0xa3 hdr=0x00 vendor = 'Nvidia Corp'
device = 'MCP55 SATA/RAID Controller (MCP55S)'
class = mass storage
subclass = RAID
atap...@pci0:0:5:2: class=0x010485 card=0x161115d9 chip=0x037f10de
rev=0xa3 hdr=0x00 vendor = 'Nvidia Corp'
device = 'MCP55 SATA/RAID Controller (MCP55S)'
class = mass storage
subclass = RAID
The other two (ad16 and ad18, the chassis has 8 slots and the last two
were only intended to be used in situtations like the one I have now) are
connected to an extra pci card:
atap...@pci0:3:6:0: class=0x010401 card=0x02409005 chip=0x02401095
rev=0x02 hdr=0x00 vendor = 'Silicon Image Inc (Was: CMD Technology
Inc)' device = 'SATA/Raid controller(2XSATA150) (SIL3112)'
class = mass storage
subclass = RAID
Meanwhile I took out the ad18 drive again and tried to use a different
drive. But that was listed as "UNAVAIL" with corrupted data by zfs.
Probably it already branded the disk for resilvering and is looking for
exactly this one now. I also put in the disk which caused the problem
above again. The resilvering process started again, but very soon the
drive got detached again resulting in the same situation I described above.
Any help is greatly appreciated.
