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....

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 mount...

hail, I have an old AthlonXP 1700+ running 7-STABLE: FreeBSD xxx 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #1: Thu Nov 13 23:54:59 BRT 2008 root@xxx:/usr/obj/usr/src/sys/xxx i386 where I have two 750GB Seagate SATA Disks. They are divided as two slices, around the first 120GB are gathered in gmirror, and what left is in gstripe. so that's whats going on. if the machine locks, and fsck comes to make its job, the box just gets slower and slower till I have to reset it the hard way. to make it not lock after just 5 minutes I have to boot and umount the "arrays", and then run fsck_uf...

Hi, We're using gmirror on our sun fire x2100 and FreeBSD 6.1-p10.

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) devfs on /dev (devfs, local) /dev/mirror/m0s3a on /etc (ufs, local) /dev/mirror/m0s3d on /var (ufs, local, soft-updates) hd30# boot0cfg -v /dev/mirro...

I upgraded from 6.2 to 6.3 p5 last night. Upon rebooting, the second disk in the mirror is missing. # atacontrol status ar0 ar0: ATA RAID1 status: DEGRADED subdisks: 0 ad0 ONLINE 1 ---- MISSING # grep ata /var/run/dmesg.boot ad0: 238475MB <WDC WD2500AVJB-63UDA0 00.02C01> at ata0-master UDMA100 ad1: 238475MB <WDC WD2500AVJB-63UDA0 00.02C01> at ata0-slave UDMA100 ar0: disk0

...onsistently that I can reboot easily (ie; not a production/client server). No matter what I do: reboot shutdown -p shutdown -r This specific server will stop at "All buffers synced" and not actually power down or reboot. KB input seems to be ignored. This server is a ZFS NAS (with GMIRROR for boot blocks) but the other boxes which show this are using GMIRRORs for root/swap/boot (no ZFS). Here is what happens on the console: http://i.imgur.com/1H8JMyB.jpg When I reset the server it appears that disks were not dismounted cleanly ... on this ZFS box it comes back quick because ZFS...

...se disks on the slave machine so that in the event the master goes down, the slave can pick up serving the samba shares (I am using CARP as the samba server IP address). My initial thought was to have the slave set up as an iscsi target and then have the master connect to each drive, then create a gmirror or zpool mirror using local_data1:iscsi_data1, local_data2:iscsi_data2, and local_data3:iscsi_data3. After some feedback (P.French for example) it would appear as though iscsi may not be the way to go for this as it locks up when the target goes down and even though I may be able to remove the targ...

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=WD...

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. Ping response stops (after 3), no CAD response, CDROM draw doesn't open! This may well be a foolish thing to do but another (different) amd64 box doesn't hang. I don't believe t...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There has been a lot of discussion on these two mailing lists about the upcoming EoL of FreeBSD 4.x which I mentioned in my email entitled "HEADS UP: FreeBSD 5.3, 5.4, 6.0 EoLs coming soon". Now that everybody (hopefully) has had their say, I'd like to offer some background and explanation. The concept of "security branches"

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/

When i use zpool labelclear, it wipes the whole disk including gpt data. So the whole disk is empty and i need to create the gpt partitions again. Is this supposed to work like this? The man page suggests that it only wipes the ZFS metadata. zpool labelclear [-f] device Removes ZFS label information from the specified device. The device must not be part of an active pool

Hi, I'm using a recent RELENG_6 under I386/SMP (Athlon X2 4800+). dmesg output is under http://people.freebsd.org/~mr/dmesg.log.gz Root is on gmirror volume (2 SATA disks), a backup FS is on graid3 (5 firewire disks). This server acts as an bacula server. During backup with bacula I discovered an complete system freeze (no keyboard, nfs, disk...) after the following lines on the screen: ... ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=1...
