draid support?

[heinowalther]

Hi there
I am just testing zfswatcher, and right away I get an issue, maybe because I use a draid pool and maybe because right now it is resilvering...
Platform:
Ubuntu 22.04
zfs-2.1.5-1ubuntu6~22.04.1
zfs-kmod-2.1.5-1ubuntu6

I see this error in the syslog:
Jul 26 16:18:05 box zfswatcher[1013799]: invalid line 7 in status output: scan: resilver (draid3:19d:24c:2s-0) in progress since Mon Jul 24 19:40:55 2023

Here is a view of my pool:
`root@box:~# zpool status aggr0
pool: aggr0
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

The 0a-xx device names are done using the vdev_id.conf file, maybe that can also cause issues?
I'm using a NetApp disk shelf and the numbers match the location in the disk shelf which is nice :-)
