If i want `zpool labelclear`, how do i define the device for this?

blue-cat: You could start with "zpool import" (as root), which should find any ZFS pools that _could_ be imported and print them. You can also look at the output of "diskinfo", which should list disks that the system can see.

zpool import says rpool ONLINE c1d0 OLPINE

*in config:

but i still don't understand what im supposed to specify as a device.

`zpool labelclear -f c1d0` failed to clear label for /dev/dsk/c1d0s0

why doesn't it work

why is that?

Does someone know?

[illumos-gate] 16663 pmap heap overflow if new LWP appears -- Andy Fiddaman <illumos⊙fn>

blue-cat: try 'zpool labelclear /dev/rdsk/c1d0s0'.

in addition to the "zpool import" thing mentioned above, you can check for the presence of a ZFS label in a partition with "zdb -l"

try something like 'zdb -l /dev/rdsk/c1d0s0'

The fact that it's listing as "rpool" suggests you're booted from that pool

I think?

Oh I suppose it would say ONLINE in the import output just because it's not DEGRADED/FAULTED

It might be that the device is not c1d0 in whatever is currently booted

or, more likely, it's not a whole disk pool, so the pool might be on s1

sommerfeld: # zpool labelclear -f /dev/rdsk/c1d0s0    returns: failed to clear label for /dev/rdsk/c1d0s0

`# zdb -l /dev/dsk/c1d0` returns failed to unpack label 0 failed to unpack label 1 failed to unpack label 2 failed to unpack label 3

same for `# zdb -l /dev/dsk/c1d0s0`

sad

how many disks and pools you have? if you have just 2 disks and 2 pools (one rpool used for current OS instance), then check which disk is used for rpool and labelclear the other disk (get name from output of format or iostat -n or diskinfo)

rmustacc: nice

It's a start at least. More to come when I get some more time.

tsoome: im from usb. and i cant labelclear

i sent a link with the output and few messages

it was about failed for some unknown reason

yes, I understand that you do get errors from labelclear. btw, what do you get from zdb -l /dev/dsk/c1d0s1 (assuming there is c1d0)?

outputs some text, not failed

there are your labels then.

in short, labelclear has bug. it would be nice if you can report the problem illumos.org/issues

tsoome supposedly it should work with the s1 omitted

exactly.

I also don't understand why the import doesn't show s1

because the pool is created on "whole" device, in which case the slice name is omitted.

im not sure about that honestly

with zdb -l, you can see the whole disk flag is 1 and you can also see the full disk name with slice included

zdb -l failed labels for whole disk as i mentioned before

yes, thats why I did ask output from zdb -l /dev/dsk/c1d0s1

i also found some information coda.io/@ff0/home-lab-data-vault/clearing-old-zfs-labels-22

also, if you check the partition table on that disk, you would see ESP (EFI System Partition) on s0

yeah

they're talking about the lack of wipefs in link i shared

even though yesterday and the day before yesterday, people here told me otherwise.

why call it wipefs, if it wont touch data in partition? and why you need wipefs, if you have dd:P (man7.org/linux/man-pages/man8/wipefs.8.html)

wipefs is wipefs not dd

i dont mean lack

wrong word

i dont know english good
