comment NFSv4 with idmap
did you ever find a solution? I seem to have the same problem with some linux distros, but not others.

comment HP MDS 600 compatibility questions
@ewwhite I did get the MDS600 and for the main pools (2) I used SAS 3TB drives. I also have some 3-4TB SATA drives that are also in the box (but not part of the pools) and they haven't seem to have caused any problems.

comment Can I remove a vdev from a ZFS pool by rolling back?
So technically you could remove the new vddv, forge the labels on the remaining vdevs, import the pool (with damaged data), and then rollback to the state when all the data was on the previous vdevs?

By 'design of ZFS' I meant, my (mis)understanding that all the FS metadata is also treated just like regular data (checksumming, striping, etc.)

comment Can I remove a vdev from a ZFS pool by rolling back?
the pool is backed up and no mistake has been made. When I said 'curiosity' I meant it. It seems perfectly reasonable to wonder if such an action might work given the design of ZFS. Technically rolling back to a pre-new vdev mistake would return to all the data being on the original vdev.... we never got our BPR after all.

comment Can I remove a vdev from a ZFS pool by rolling back?
Given the design of ZFS I would imagine rolling back to a snapshot when all the data was on one vdev, would mean that all the data would again be on that single vdev, including FS metadata, which means you could technically remove the new vdev without losing data. Now wether the tools would allow you to is another question. Anyways, I tested this out on a test pool and zpool import -F failed.

comment Can I remove a vdev from a ZFS pool by rolling back?
I didn't do anything. As mentioned this was merely curiosity. I was recently adding a vdev to a production pool, and while double checking the command wondered if there was a way it could be undone. BTW, it went just fine.

comment Resolve hostname without FQDN
This solutions seems somewhat inelegant. I'm thinking of upgrading my dnsmasq install with master/slave bind9... I know in dnsmasq one can specify the domain and expand-hosts option to achieve the same thing without having to use dhcp to set a search domain.

comment NFS server refusing hostname that is allowed
i suppose the other options is to move the list of hosts that dnsmasq uses to a file other than /etc/hosts? Seems like more work.

@mgorven Thanks, I think I know what you might be getting at. The /etc/hosts file was shorting DNS lookup.
