Hi, all,
I have a system with 12 S-ATA disks attached that I set up
as a raidz2:
%zpool status zfs
pool: zfs
state: ONLINE
scrub: scrub in progress for 0h5m, 7.56% done, 1h3m to go
config:
NAME STATE READ WRITE CKSUM
zfs ONLINE 0 0 0
raidz2 ONLINE 0 0 0
da0 ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0
da3 ONLINE 0 0 0
da4 ONLINE 0 0 0
da5 ONLINE 0 0 0
da6 ONLINE 0 0 0
da7 ONLINE 0 0 0
da8 ONLINE 0 0 0
da9 ONLINE 0 0 0
da10 ONLINE 0 0 0
da11 ONLINE 0 0 0
errors: No known data errors
We are currently tweaking kernel memory a bit but the on disk
data and the hardware seem to be just fine.
7-STABLE, amd64, 4 GB of RAM.
A couple of days ago, at each boot we saw this error message:
GEOM: da0: corrupt or invalid GPT detected.
GEOM: da0: GPT rejected -- may not be recoverable.
There should not be any partition, MBR or GPT on the disks,
I created the zpool on the raw devices.
So I figure:
Somehow zfs wrote some data to da0 that somewhat resembles a
GPT partition table, so GEOM gets confused at boot time.
Question is: can somebody confirm my guess? If yes should I
just ignore the message, can it be disabled somehow (compile
kernel without GPT?) or should zpools be created on slices instead
of disks?
Thanks for any hints,
Patrick
