Re: [zfs-discuss] ZFS slows down over a couple of days

2011-01-12 Thread SR
You may need to adjust zfs_arc_max in /etc/system to avoid memory contention

Re: [zfs-discuss] ZFS - Sudden decrease in write performance

2010-11-21 Thread SR
This is probably the same write throttle issue which has been discussed to 
length on this list. Check the archives for zfs write throttle, especially 
posts from Jun-Jul 2009.

[zfs-discuss] SUNWzfsg missing in Solaris 11 express?

2010-11-18 Thread SR
SUNWzfsg (zfs admin gui) seems to be missing from Solaris 11 express.  Is this 
no longer available or has it been integrated with something else?

What if you connect locally via NFS or iscsi?

[zfs-discuss] Mirroring a zpool

2010-10-28 Thread SR
I have a raidz2 zpool which I would like to create a mirror of.

Is it possible to create a mirror of a zpool?

I know I can create multi way mirrors of vdevs, do zfs/send receive etc.. to 
mirror data.   But can I create a mirror at the zpool level?

Thanks
SR

Re: [zfs-discuss] Performance issues with iSCSI under Linux

2010-10-08 Thread SR
To see if it is iscsi related or zfs, have you tried to test performance over 
nfs to a zfs filesystem instead of a zvol?

I'm curious why nexenta did not perform as well as opensolaris.  Both OS 
versions seem to be the same.

Are there any utilities built into Opensolaris and/or ZFS to update disk drive

Thanks
