I appologize if this has been answered already, but I've tried to RTFM and
haven't found much. I'm trying to get HDS shadow copy to work for zpool
replication. We do this with VXVM by modifying each target disk ID after
it's been shadowed from the source LUN. This allows us to import each

I'll have to recreate the situation (won't be able to do so until next
week). I had a zpool status (

Hi Glenn,
Where is it hanging? Could you provide a stack trace? It's possible
that it's just a bug and not a configuration issue.

I had a disk that contained a zpool. For reasons that we won't go in
to, that disk had zero's written all over it (at least enough to cover
the entirety of the zpool space). Now when I run zpool status the
command hangs when it tries to display information about the now
non-existent pool. Simila

I believe this is just:
zfs set sharenfs='root=host1:host2,[EMAIL PROTECTED]/24:@10.9.9.5' filesystem
See the man pages for zfs(1M) (especially the last example) and share_nfs(1M).

Try something like this:
zsfs set sharenfs=options mypool/mydata
where options is:
sharenfs="[EMAIL PROTECTED]/24:@10.9.9.5/32,[EMAIL PROTECTED]/24:@10.9.9.5/32"

I¹m sure I¹m missing something basic here. I need to do the following
things, and can¹t for the life of me figure out how:
1. Export a zfs filesystem over NFS, but restrict access to a limited set of
hosts and/or subnets: ie: 10.9.8.0/24 and 10.9.9.5 in.
2. give root access to a zfs file sys

Hi,

IIRC, maildir MTAs never overwrite mail files. But courier-imap does maintain
some additional index files which will be overwritten and I guess other IMAP
servers will probably do the same.

Not knowing of a better place to put this, I have created

Please make any corrections there.
