Hello all.
I noticed that the autoreplace function is not working in FreeBSD.
So after some search on the net i believe this has not been implemented.
Should ZFS not warn users that put a a spare in the pool that this is
NOT a hot spare, and human intervention is needed to put the spare in place.
I think that a lot of users could get false sence of secutity.
In case of the auto replace, i think the pool must not insert the spare
when an administrator sets a drive offline!
Only when a drive fails, and goes to UNAVAIL or REMOVED state.
For me, and i think others having hot spares is almost an normal thing
to have, especially with an advanced system as ZFS.
Also does anyone have a script that can do this.
My scripting capabilities are as close to non existing..
Secondly devd.
Are the entries in /etc/devd.conf accurate?
if i see enries in /var/run/devd.pipe, the all look like.
!system=ZFS subsystem=ZFS type=misc.fs.zfs.config_sync.
the entry's in devd.conf do not contain the subsystem entry.
notify 10 {
match "system" "ZFS";
match "type" "data";
action "logger -p kern.warn 'ZFS: zpool I/O failure, zpool=$pool
error=$zio_err'";
};
should they not contain the following line also?
match "subsystem" "ZFS"
if i convert the above example to detect a state change , no entry in
the log.
notify 10 {
match "system" "ZFS";
match "type" "resource.fs.zfs.statechange";
action "logger -p kern.warn 'ZFS: State has chaged on , zpool=$pool'";
};
if i add the line match "subsystem" "ZFS" then i get the warning in my
/var/log/messages.
notify 10 {
match "system" "ZFS";
match "subsytem" "ZFS";
match "type" "resource.fs.zfs.statechange";
action "logger -p kern.warn 'ZFS: State has chaged on , zpool=$pool'";
};
And which match type is there for a removed or unavailable drive?
Thanks for your patience
regards
Johan Hendriks
