[zfs-discuss] NFS performance issue

2010-09-08 Thread Dr. Martin Mundschenk
Hi! I searched the web for hours, trying to solve the NFS/ZFS low performance issue on my just setup OSOL box (snv134). The problem is discussed in many threads but I've found no solution. On a nfs shared volume, I get write performance of 3,5M/sec (!!) read performance is about 50M/sec

[zfs-discuss] ZFS Storage server hardwae

2010-08-25 Thread Dr. Martin Mundschenk
Hi! I'm running a OSOL box for quite a while and I think ZFS is an amazing filesystem. As a computer I use a Apple MacMini with USB and FireWire devices attached. Unfortunately the USB and sometimes the FW devices just die, causing the whole system to stall, forcing me to do a hard reboot. I

[zfs-discuss] Boot from external degraded zpool

2009-12-30 Thread Dr. Martin Mundschenk
Hi! I wonder if the following scenario works: I have a mac mini running as an OSOL box. The OS is installed on the internal hard drive on the vdrive rpool. On rpool there is no redundancy. If I add an external block device (USB / Firewire) to rpool to mirror the internal hard drive and if

[zfs-discuss] ZFS Kernel Panic

2009-12-12 Thread Dr. Martin Mundschenk
Hi! My OpenSolaris 2009.06 box runs into kernel panics almost every day. There are 4 FireWire drives, as a RaidZ pool attached to a MacMini. The panic seems to be related to this known bug: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6835533 Since there are no known

Hi! I tried to add an other FiweFire Drive to my existing four devices but it turned out, that the OpenSolaris IEEE1394 support doen't seem to be well-engineered. After not recognizing the new device and exporting and importing the existing zpool, I get this zpool status: pool: tank
