Hi, When I try to run the command wmix to mix two WAV files recorded by the Monitor application I get the following warning in the console and the macro exit at that point. Running the command from a standard system console it works. More, even from this macro it works and produce a valid mixed file, but still get that error and the macro cannot continue. Why? I have tried even with a simple

Hi, So the case is, now I''ve got a btrfs image file, which is created from a raid0 btrfs fs. And if I run ''btrfs-image -r image_file /dev/sdf'', then I have to mount it with ''degraded'' mode, and that still fails because raid0 requires two disks at least. So any ideas how to make it work? thanks, liubo -- To unsubscribe from this list: send the line

I just noticed something very strange on one of our Dell PE1750 servers. It is running FreeBSD 4-STABLE on dual CPU's with the embedded Dell Raid controller (amr driver). Attached are 3 disks of 145GB. On a RAID5 logical drive this gives me ~280GB storage. Up until the last reboot (35 days ago) the 'amrcontrol' status utility gave me: Logical drive 0 Stipes blah Size blah

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

Hey! I have big problem with my centos 5.1. I have two hard discs 500gig and 40gig and those are in RAID0. I would like to remowe the small 40gig hd and put new 500gig hd and i don't wan't raid0 anymore. How can i copy data from 40gig hd to 500gig hd and switch 40gig hd to new 500gig hd? Another question: Can i just copy all my files to windows laptop and if i wan't

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.

is it RAID 0 (striped) or raid1 (mirrored) ?? if you wrote on half of a raid0 stripe set, you basically trashed it. blocks are striped across both drives, so like 16k on the first disk, then 16k on the 2nd then 16k back on the first, repeat (replace 16k with whatever your raid stripe size is). if its a raid 1 mirror, then either disk by itself has the complete file system on it, so you should be

I'm trying to work out the kinks of a proprietary, old, and clunky application that runs on CentOS. One of its main problems is that it writes image sequences extremely non-linearly and in several passes, using many CPUs, so the sequences get very fragmented. The obvious solution to this seems to be to use SSDs for its output, and some scripts that will pick up and copy our the sequences

Hello, i recently installed Centos 5 on a new server with a single scsii disk. After the installation, i added 2 additional disks that were once the components of a raid0 array on another server. I get some errors and am unable to start the array the following is an extract from dmesg output: md: Autodetecting RAID arrays. md: could not open unknown-block(8,17). md: could not open

How can I verify the read speed of a btrfs raid0 pair in archlinux.? I assume raid0 means striped activity in a paralleled mode at lease similar to raid0 in mdadm. How can I measure the btrfs read speed since it is copy-on-write which is not the norm in mdadm raid0.? Perhaps I cannot use the same approach in btrfs to determine the performance. Secondly, I see a methodology for raid10 using

Hi all, I am using a Sangoma with two PRI's.

My computer running CentOS 7 is configured to use BIOS RAID0 and has two identical SSDs which are also encrypted. I had a crash the other day and due to a bug in the operating system update, I am unable to boot the system in RAID mode since dracut does not recognize the disks in grub. After modifying the grub command line I am able to boot the system from one of the harddisks after entering the

Hi, I do have a disk array that is providing striped LUNs to my Solaris box. Hence I''d like to simply concat those LUNs without adding another layer of striping. Is this possibile with ZFS? As far as I understood, if I use zpool create myPool lun-1 lun-2 ... lun-n I will get a RAID0 striping where each data block is split across all "n" LUNs. If that''s

I''ve been monitoring the lists for a while now but didn''t see this problem mentioned in particular: I''ve got a fairly standard desktop system at home, 700gb WD drive, nothing special, with 2 btrfs filesystems and some snapshots. The system runs for days, and I''ve noticed unusual disk activity the other evening - turns out that it''s taking forever to

i''ve got a little zpool with a naughty raidz vdev that won''t take a replacement that as far as i can tell should be adequate. a history: this could well be some bizarro edge case, as the pool doesn''t have the cleanest lineage. initial creation happened on NexentaCP inside vmware in linux. i had given the virtual machine raw device access to 4 500gb drives and 1 ~200gb

I''ve created a test volume and copied a bulk of data to it, however the results of the space allocation are confusing at best. I''ve tried to capture the history of events leading up to the current state. This is all on a Debian Wheezy system using a 3.10.5 kernel package (linux-image-3.10-2-amd64) and btrfs tools v0.20-rc1 (Debian package 0.19+20130315-5). The host uses an

Hi, I have 4 machines, all converted to BTRFS about 6 months ago, now all running Ubuntu Quantal with kernel 3.5.0-17 The matter is that all these machines are now getting slower and slower everyday, every disk access causing the disk to be 100% busy for long periods, to the point that I''m now seriously considering migrating everything back to ext4... From the start BTRFS was "not
