If it does, the addition of an SSD-based ZIL / slog device would most certainly help. Maybe you could describe the makeup of your zpool as well? Ray The zpool is a mirrored root-pool (2 SATA 250GB devices). The box is a Dell PE T710. When I copy via NFS, zpool iostat reports 4MB/sec along the copy process. When I copy via scp I get a network performance of about 50 MB/sec and zpool iostat reports 105 MB/sec for a short interval about 5 seconds after scp completed. As far as I figured out, the problem is the nfs commit, that forces the filesystem to write data directly on disk instead of caching the data stream, like it is done in the scp example. NFS was there long before SSD-based drives where. I can not imagine, that NFS performance used to be not more than 1/3 of the speed of a 10BaseT connection ever before...

[zfs-discuss] NFS performance issue
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 is ok but on a GBit network, more should be possible, since the servers disk performance reaches up to 120 M/sec. Does anyone have a solution how I can at least speed up the writes? Martin ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS Storage server hardwae

You have to scrap your mini, and use internal (or hotswappable) disks. Never expect a mini to be reliable. They're designed to be small and cute. Not reliable. The MacMini and the disks themselves are just fine. The problem seems to be the SATA-bridges to USB/FW. They just stall, when the load gets heavy.

[zfs-discuss] ZFS Storage server hardwae
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 had the worst experience with an USB-SATA bridge running an Oxford chipset, in a way that the four external devices stalled randomly within a day or so. I switched to a four slot raid box, also with USB bridge, but with better reliability. Well, I wonder what are the components to build a stable system without having an enterprise solution: eSATA, USB, FireWire, FibreChannel?

Re: [zfs-discuss] Cant't detach spare device from pool
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 complete before you can detach the spare.

Re: [zfs-discuss] Drive failure causes system to be unusable
Am 08.02.2010 um 20:03 schrieb Richard Elling: Are you sure there is not another fault here? What does svcs -xv show? Well, I don't have the result of svcs -xv, since the fault is recovered by now, but it turned out not to be a hardware failure but an unstable USB-conectivity. But sill: Why does the system get stuck? Even when a USB-Plug is unhooked, why does the spare does not go online?

[zfs-discuss] Drive failure causes system to be unusable
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 to a directory on the pool causes the tty to get stuck 3. no reboot was possible 4. the system had to be rebooted ungracefully by pushing the power button After reboot: 1. The zpool ran in a degraded state 2. the spare device did NOT automatically go online 3. the system did not boot to the usual run level, and no auto-boot zones where started, GDM did not start either NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 0 raidz1-0 DEGRADED 0 0 0 c21t0d0 ONLINE 0 0 0 c22t0d0 ONLINE 0 0 0 c20t0d0 FAULTED 0 0 0 corrupted data c23t0d0 ONLINE 0 0 0 cache c18t0d0ONLINE 0 0 0 spares c16t0d0AVAIL My questions: 1. Why does the system get stuck, when a device faults? 2. Why does the hot spare not go online? (The manual says, that going online automatically is the default behavior) 3. Why does the system not boot to the usual run level, when a zpool is in a degraded state at boot time?

[zfs-discuss] Boot from external degraded zpool
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 internal hard drive fails, can I reboot the system with the detached internal drive but with the degraded mirror half on the external drive? The mac is definitely capable of booting from all kinds of devices. But does OSOL support it in such a way, described above?

[zfs-discuss] ZFS Kernel Panic
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, is my hardware configuration worthless?

[zfs-discuss] Messed up zpool (double device label)
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: DEGRADED status: One or more devices could not be used because the label is missing or invalid.
