[zfs-discuss] zfs snapshot stalled?

2008-10-19 Thread Carsten Aulbert
Hi all, I've just seen something weird. On a zpool which looks a bit busy right now (~ 100 read op/s, 100 kB/s) I started a zfs snapshot about an hour ago. Until now, a taking a snapshot took usually at few seconds at most even for largish ~TByte file systems. I don't know if the read IOs are curr

[zfs-discuss] ZFS scalability in terms of file system count (or lack thereof) in S10U6

2008-10-19 Thread Paul B. Henson
I originally started testing a prototype for an enterprise file service implementation on our campus using S10U4. Scalability in terms of file system count was pretty bad, anything over a couple of thousand and operations started taking way too long. I had thought there were a number of improveme

[zfs-discuss] Booting 0811 from USB Stick

2008-10-19 Thread W. Wayne Liauh
I was able to install os0805 into a USB stick and boot from it. It works really great. However, after image-updating to build 95, I am only seeing the GRUB prompt. I have also installed the 0811_95 LiveDVD into a USB stick, but the machine just keeps rebooting itself. -- This message posted fr

[zfs-discuss] Recover after disk labels "failure"

2008-10-19 Thread Oleg Muravskiy
I have a zfs pool made of two vdevs, each using one whole physical disk, under OpenSolaris 2008.5. Disks live on a Netcell SATA/RAID controller, that has three ports (and I planned to use three disks there, and configure mirrors in zfs), but as it turned out could only provide one or two disks t

2008-10-19 Thread Nigel Smith
With ZFS, that are 4 identical labels on each physical vdev, in this case a single hard drive. L0/L1 at the start of the vdev, and L2/L3 at the end of the vdev. As I understand it, part of the reason for having four identical labels is to make it difficult to completely loose the information in th

[zfs-discuss] ZFS write performance on boot disk

2008-10-19 Thread William Bauer
I apologize if this has been addressed countless times, but I have searched & searched and have not found the answer. I'm rather new to ZFS and have learned a lot about it so far. At least one thing confuses me, however. I've noticed that writes to the boot disk in OpenSolaris (i.e. pool rpoo

Hi, I'm running FreeBSD 7.1-PRERELEASE with a 500-gig ZFS drive. Recently I've encountered a FreeBSD problem (PR kern/128083) and decided about updating the motherboard BIOS. It looked like the update went right but after that I was shocked to see my ZFS destroyed! Rolling the BIOS back did not
