Hi, When trying to attach a created volume to an instance using the virsh utility I am running into this error :- [] $ sudo virsh attach-device instance-00000015 disk.xml error: Failed to attach device from disk.xml error: internal error unable to execute QEMU command '__com.redhat_drive_add': Device 'drive-virtio-disk21' could not be initialized For experimental purpose I

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College of Life Sciences Computer Support Brigham Young University leblanc at

I''m evaluating lustre. I''m trying what I think is a basic/simple ethernet config. with MDT and OST on the same node. Can someone tell me if the following (~150 second recovery occurring when small 190 GB OST is re-mounted) is expected behavior or if I''m missing something? I thought I would send this and continue with the eval while awaiting a response. I''m using

Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota

Chris, Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

Hi All, I am facing problem with E1 line. I have installed Asterisk (1.4.20.1) on a system with Digium TE420 card (Zaptel- 1.4.10) But every now and then I face problem of down E1's. The log show lot of entries like "pri_dchannel: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2" This happens on a regular basis and the E1 becomes up after some time. My

We are running a benchmark that does single threaded 512 KB writes to a LUN on a CLARiiON storage array. The dual Xeon host (Dell 2650) with 4 GB of memory runs RHEL 4U3 We measured the write bandwidth for writes to the block device corresponding to the lun (e.g. /dev/sdb), a file in an ext2 filesystem and to a file in an ext3 file system. Write b/w for 512 KB writes Block device 312 MBps Ext2

Hi, I could not find this anywhere else reported, so here we go: creating a new btrfs filesystem (btrfs-progs-unstable from git) and mounting it succeeds, unmounting however fails with the kernel messages attached to this mail. After that, I can still read and write to the btrfs mount, but e.g. /bin/sync never finishes, sysrq-s never reports "Sync complete". I''m using a

All, I'm requesting comments from the expert readers of ext3-users on these notes for tuning ext3 for performance. Most helpful would be feedback pertinent to RHEL 5; as XFS isn't supported under Red Hat Enterprise Linux these items are an attempt to match XFS performance with ext3. These items were culled from a number of sources. Will they be effective for achieving the performance

Hello, I have a production script that do read operations to a lot of small files. I read that one can gain performance boost with small files by using a loop device on top of Lustre. So a created 500 GB file striped across all of my OSTs(which are 8). I formatted the file with ext2 fs, and mounted it on a client. Just for the sake of testing a simple bash script finds all files with a given file

Hi, I'm trying to add mysql CDR onto a vanilla Asterisk 1.2 install. The add-ons pack has been installed for a while, so now I'm trying to add the Mysql config. I've created a mysql database, added the grants for a user acces, and can run a mysql -u asteriskcdruser -p and can connect to the database. I've been using this as a guide:

Hello, 1) when compiling the lustre modules for the server the ./configure script behaves a bit odd. The --enable-server option is silently ignored when the kernel is not 100% patched. Unfortunatly the build works for the server, but during the mount the error message claims about a missing "lustre" module which is loaded and running. What is really missing are the ldiskfs et al

When I try to build wine 1.1.15 in Fedora 8 I get this error > sh: i686-redhat-linux-gnu-as: command not found > winebuild: i686-redhat-linux-gnu-as failed with status 32512 > winegcc: ../../tools/winebuild/winebuild failed > make[2]: *** [acledit.dll.so] Error 2 > make[2]: Leaving directory `/home/user/rpmbuild/BUILD/wine-1.1.15/dlls/acledit' > make[1]: *** [acledit] Error

My application always needs to sync file data after writing. I don't want anything handing around in the kernel buffers. I am wondering what is the best method to accomplish this. 1. Do I use EXT2 and use fdatasync() or fsync()? 2. Do I use EXT2 and mount with the "sync" option? 3. Do I use EXT2 and use the O_DIRECT flag on open()? 4. Do I use EXT3 in full journaled mode,

I'm setting up a new file server and I just can't seem to get the expected performance from ext3. Unfortunately I'm stuck with ext3 due to my use of Lustre. So I'm hoping you dear readers will send me some tips for increasing ext3 performance. The system is using an Areca hardware raid controller with 5 7200RPM SATA disks. The RAID controller has 128MB of cache and the disks

Hi, everyone, I need some help in figuring out what may have happened here, as newly created files on an OST are being corrupted. I don''t know if this applies to all files written to this OST, or just to files of order 2GB size, but files are definitely being corrupted, with no errors reported by the OSS machine. Let me describe the situation. We had been running Lustre 1.8.4 for

Dear all, I am trying to import a SAS file into R (in fact I only need the value labels from the formats file), using Hmisc package, but I get this error: my.sas <- sas.get("/home/adi/3", "fis1_sgg") sh: sas: not found Error in sas.get("/home/adi/3", "fis1_sgg") : SAS job failed with status 32512 I read some past discussions and I get the impression
