Guys,
What is the best way to ask for a feature enhancement to ZFS.
To allow ZFS to be usefull for DR disk replication, we need to be able
set an option against the pool or file system or both, called close
sync. ie When a programme closes a file any outstanding writes are flush
to disk,

Does opensolaris iSCSI target support SCSI-3 PGR reservation ?
My goal is to use the iSCSI LUN created by [1] or [2] as a quorum device for a
3-node suncluster.
[1] zfs set shareiscsi=on storage-pool/zfs volume name
[2] iscsitadm create target .
Thanks,

As far as I can tell, and it is part of the iSCSI RFC. Source code is at

If you look at callers of remove_mountpoint() in libzfs, you'll see that
it does remove the mountpoint, but only for inherited or default
directories. We have no way to know for sure whether the mountpoint was
originally created by ZFS or not, so we can only guess based on the
current mountpoint.

Hi Wee Yeh,
Thanks for the earlier tips on July17th. I have a couple questions...
I followed your suggestion and first created two raid0 volumes.
volume capacity raid data standby
v0 134.890 GB 0 u1d1-4none
v1 168.613 GB 0
I'm looking to use ZFS to store about 6-10 live virtual machine images
(served via VMWare Server on Linux) and network file storage for ~50 Windows
clients. I'll probably start at about 1TB of storage and want to be able to
scale to at least 4TB. Cost and reliability are my two greatest concerns.
First, does RaidZ support disks of multiple sizes, or must each RaidZ set
consist of equal sized disks?
Each RAID-Z set must be constructed from equal-sized storage. While it's
possible to mix disks of different sizes, either you lose the capacity of the
larger disks, or you have to partition
I'd implement this via LD_PRELOAD library [ ... ]
There's a problem with sync-on-close anyway - mmap for file I/O. Who
guarantees you no file contents are being modified after the close() ?
The latter is actually a good argument for doing this (if it is necessary) in
the file system, rather
A quick look through the source would seem to indicate that the PERSISTENT
