Hi, I''m running OpenSuse 12.2 with kernel 3.5.3 HBA= LSI 1068e using the MPTSAS driver (patched) (https://patchwork.kernel.org/patch/1379181/) SANOS1:/media # uname -a Linux SANOS1 3.5.3 #3 SMP Sun Sep 2 18:44:37 CEST 2012 x86_64 x86_64 x86_64 GNU/Linux I''ve tried to simulate a disk replacement but it seems that now /dev/sdg is stuck in the btrfs pool (RAID10) SANOS1:/media #

Hi all, Last week we had 2 times an "uncorrectable ecc memory error" crash on our server on the same memory module. After removing the faulty module and restarting the server, everything was working again. However, yesterday we had a soft lockup and had to restart the server again. No warning or ecc error this time. Everything is working now, but we want to avoid this in the future

Hi, I have a Btrfs RAID 10 (data and metadata) file system that I believe suffered a disk failure. In my attempt to replace the disk, I think that I've made the problem worse and need some help recovering it. I happened to notice a lot of errors in the journal: end_request: I/O error, dev dm-11, sector 1549378344 BTRFS: bdev /dev/mapper/Hitachi_HDS721010KLA330_GTA040PBG71HXF1 errs: wr

Hello, on a fs with 4 disks, raid 10 for data, one drive was failing and has been removed. After reboot and ''mount -o degraded...'', the fs looks full, even though before removal of the failed device it was almost 80% free. root@fs0:~# df -h /mnt/b Filesystem Size Used Avail Use% Mounted on /dev/sde 11T 2.5T 41M 100% /mnt/b root@fs0:~# btrfs fi df /mnt/b Data,

Greetings, until yesterday I was running a btrfs filesystem across two 2.0 TiB disks in RAID1 mode for both metadata and data without any problems. As space was getting short I wanted to extend the filesystem by two additional drives lying around, which both are 1.0 TiB in size. Knowing little about the btrfs RAID implementation I thought I had to switch to RAID10 mode, which I was told is

Hi! The problem is that the BTRFS raid10 filesystem without any understandable cause refuses to mount. Here is dmesg output: [77847.845540] device label linux-btrfs-raid10 devid 3 transid 45639 /dev/sdc1 [77848.633912] btrfs: allowing degraded mounts [77848.633917] btrfs: enabling auto defrag [77848.633919] btrfs: use lzo compression [77848.633922] btrfs: turning on flush-on-commit [77848.658879]

Greetings! I''m testing raid6, and recently added two drives. I haven''t been able to properly resume a balance operation: the number of total chunks is always too low. It seems that the balance starts and pauses properly, but always resumes with ~7 chunks. Here''s an example: vendikar tim # uname -r 3.10.0-031000rc4-generic vendikar tim # btrfs fi sho Label:

Hi there... I have kernel version 2.6.36.3, compiled with gcc 4.4.5, btrfstools version 0.19+20101101 I have a btrfs filesystem (/data) consisting of two 1TB hard disks, raid0.

I have two disks that I formatted as btrfs RAID0 on opensuse 11.3. The raid worked well several days until there was a power surge. The system successfully rebooted and the btrfs raid reappeared, but the kernel occasionally threw oops. That was my first experience with oops. After two days, the btrfs raid failed to mount via fstab and when I manually tried to mount it, there was a kernel

Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata.

Sorry for the long post but I know trying to decide on hardware often want to see details about what people are using. I have the following AS-2022G-URF machine running OpenGaryIndiana[1] that I am starting to use. I successfully transferred a deduped zpool with 1.x TB of files and 60 or so zfs filesystems using mbuffer from an old 134 system with 6 drives - it ran at about 50MB/s or

I would like to set up CentOS on 4 SATA hard drives that I would like to configure in RAID10. I read somewhere that Raid10 support is in the latest kernel, but I can't seem to get anaconda to let me create it. I only see raid 0, 1, 5, and 6. Even when I tried to set up raid5 or raid1, it would not let me put the /boot partition on it, and I though that this was now possible. Is it

We have DELL R910 with H800 adapter in it. several MD1220 connect to H800. Since MD1220 have 24 hard disks in it. When I configured RAID10, there is a choice call 'single spanned virtual disk" (22 disks). Can anyone tell me how "single spanned virtual disk" work? Any document relate to it? Thanks.

Hello! I have a 1 TB ext4 drive that''s quite full (~50 GB free space, though I could free up another 100 GB or so if necessary) and two empty 0.5 TB drives. Is it possible to get another 1 TB drive and combine the four drives to a btrfs raid10 setup without (if all goes well) losing my data?

hi guys, gals do you know if conversion from lvm's raid10 to raid0 is possible? I'm fiddling with --splitmirrors but it gets me nowhere. On "takeover" subject man pages says: "..between striped/raid0 and raid10."" but no details, nowhere I could find documentation, nor a howto. many thanks, L.

I''ve installed Open Solaris 2009.06 on a machine with 5 identical 1TB wd green drives to create a ZFS nas. The intended install is one drive dedicated to the OS and the remaining 4 drives in a raidz1 configuration. The install is working fine, but creating the raidz1 pool and rebooting is causing the machine report "Cannot find active partition" upon reboot. Below is command

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
