Hello there! Here's my story, hopefully some of you won't follow my steps and avoid some troubles :) Yesterday I've decided that's about time to test zfs functionality on my home server PC (i386 FreeBSD 7.1-pre) . A couple of weeks ago I bought new desktop PC (with SATA), so I had a bunch of PATA disks from old one to use in server. Lucky me - there was 3 HDD at size 40GB -

hail, I write just to make sure its dead. I've lost the first disk on a ZFS pool (jbod). Now I can't mount it with only the second disk. The first disk clicks to death :( [root@optimus ~]# zpool status pool: pool state: UNAVAIL status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing

Colleagues, one of my servers had to be rebooted uncleanly and then I have backgrounded fsck locked for more than an our in snaplk: 742 root 1 -4 4 1320K 688K snaplk 0:02 0.00% fsck_ufs File system in question is 200G gmirror on SATA. Usually making a snapshot (e.g., for making dumps) consumes 3-4 minutes for that fs, so it seems to me that filesystem is in a deadlock. Any

hail, I have a soekris running an atom and 2GB RAM and ZFS using 7 drives, small capacity though, to test and study if I can make my home server this box and this way. It will be a simple server, three users tops. I followed the handbook and made the geli step on the disks: Geom name: label/zfs1.eli State: ACTIVE EncryptionAlgorithm: AES-XTS KeyLength: 128 Crypto: software UsedKey: 0 Flags:

Hi. Here you can find patches with changes to gmirror(8) and graid3(8): http://people.freebsd.org/~pjd/patches/gmirror.7.patch http://people.freebsd.org/~pjd/patches/graid3.patch The patches does the following: - Significant synchronization speed improvement. Now many parallel synchronization I/O requests can be used instead of only one before. Many people requested this. - Close race

Hi Guys, Has somebody encountered (significantly) different read/write speeds when using gmirror? I have 2xWD WD30EFRX RED drives which are configured as follows: $ gmirror status Name Status Components mirror/root COMPLETE ada0p2 (ACTIVE) ada1p2 (ACTIVE) mirror/data COMPLETE ada0p4 (ACTIVE) ada1p4 (ACTIVE) mirror/root is mounted

hail, I'd like to try it in this OS, how to do ? I saw on http://wiki.x.org/wiki/Development/git some info, but I really need to rebuild all that ? from my ports dir, I got error: nv_dri.c:263:2: error: #error nouveau_drm.h does not match expected patchlevel, update libdrm. *** Error code 1 Stop in /usr/ports/x11-drivers/xf86-video-nouveau/work/xf86-video-nouveau-0.0.10.20090129/src. ***

Hi, We're using gmirror on our sun fire x2100 and FreeBSD 6.1-p10. Some days ago I found this in the logs: Apr 1 02:12:05 x2100 kernel: ad6: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=612960533 Apr 1 02:12:05 x2100 kernel: ad6: FAILURE - WRITE_DMA48 status=51<READY,DSC,ERROR> error=10<NID_NOT_FOUND> LBA=612960533 Apr 1 02:12:05 x2100 kernel: GEOM_MIRROR:

Hello, freebsd-stable. Does somebody use some software RAID5 on FreeBSD in real production system? I want to build storage server for my home: RAW photos, multi-layer PhotoShop files and FLAC-encoded music consume a lot of space, and they should be availible both from desktop & notebook. Also, all photo-content is unique, so I need some insuranse from single HDD crash. I understand,

hail, I partitioned the disk this way: fdisk da0 ******* Working on device /dev/da0 ******* parameters extracted from in-core disklabel are: cylinders=12161 heads=255 sectors/track=63 (16065 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=12161 heads=255 sectors/track=63 (16065 blks/cyl) Media sector size

With the introduction of zfs to FreeBSD 7.0, a door has opened for more mirroring options so I would like to get some opinions on what direction I should take for the following scenario. Basically I have 2 machines that are "clones" of each other (master and slave) wherein one will be serving up samba shares. Each server has one disk to hold the OS (not mirrored) and then 3 disks, each

Hi, I have a LSI Logic sata/sas raid running, is there a way to see the state of the volume, like optimal, degraded or resyncing? I've tried several commands with camcontrol but I cant figure it out. -- Peter Ankerst?l peter@pean.org http://www.pean.org/

Hi, after one month with gmirror and gjournal running on a 7.0-RELEASE #p2 amd64 (built from latest CVS source), the box hung a couple of times when on high disk load. Finally, while building some port it won't boot for no reason obvious to me. This is what I get with kernel.geom.mirror.debug=2: ata2-master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire ad4: 476940MB <SAMSUNG HD501LJ

after trying to mount my zfs pools in single user mode I got the following message for each: May 18 09:09:36 gw kernel: ZFS: WARNING: pool 'cache1' could not be loaded as it was last accessed by another system (host: gw.bb1.matik.com.br hostid: 0xbefb4a0f).

These are new boxes. http://www.supermicro.com/products/system/1U/5015/SYS-5015B-MT.cfm core 2 Q6600 CPU 8Gb 667 RAM Boxes were memtested from Fri-Mon okay. 6.3-RELEASE (amd64) installs fine. Build cycle okay. Running (no load) for a week or so. However, when I try to configure gmirror they hang on boot. After some fiddling it appears issuing #kldload geom_mirror hangs the boxes very hard.

My backup script split filesystem dumps to files with size of 4,37 GB (4 588 544 kB). It's just an optimal size to fill out DVDs. At this moment I have to burn them from windows via smb-link becuase I didn't manage to do this task from FreeBSD console due to 2GB/4GB filesize restrictions (growisofs). I'm using freeware CDBurnerXP to burn my backups (ISO9660/UDF/Joliet), and they

Hi Rafael, Sure, the expansion of at least .cpload should be done in the Target ELFStreamer but AFAICS it doesn't solve my initial problem. MCCodeGenInfo is not created in tools where CodeGen isn't needed (llvm-mc) and it's still not possible to access the Relocation Model in MCObjectFileInfo from the target streamer (private member). Am I missing something obvious ? There are many

Hi, all, I know about the "foot shooting" prevention in geom(4) when trying to update the MBR of a mounted disk. I have a system with ad4 and ad6 mirrored and fdisk partitions residing on the mirror to be booted alterningly: hd30# gmirror status Name Status Components mirror/m0 COMPLETE ad4 ad6 hd30# mount /dev/mirror/m0s1a on / (ufs, local, read-only)
