[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 which

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 h

2010-08-21 Thread Martin Mundschenk
After about 62 hours and 90%, the resilvering process got stuck. Since 12 hours nothing happens anymore. Thus, I can not detach the spare device. Is there a way to get the resilvering process back running? Martin Am 18.08.2010 um 20:11 schrieb Mark Musante: > You need to let the resilver com

Hi! I had trouble with my raidz in the way, that some of the blockdevices where not found by the OSOL Box the other day, so the spare device was hooked on automatically. After fixing the problem, the missing device came back online, but I am unable to detach the spare device, even though all d

Hi! I have a OSOL box as a home file server. It has 4 1TB USB Drives and 1 TB FW-Drive attached. The USB devices are combined to a RaidZ-Pool and the FW Drive acts as a hot spare. This night, one USB drive faulted and the following happened: 1. The zpool was not accessible anymore 2. changing

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 the

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 state:

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 workarounds,
