Hello all, I have a problem with Xen and FibreChannel. The Dom0 can''t export a Disk on a FibreChannel SAN-Box to the DomU''s. In the DomU configuration I try: disk = [ ''phy:/dev/sdb1,/dev/sda1,w'' ] or disk = [ ''file:/mnt/sambashare.img,sda1,w'' ] sambashare.img is a 512MB great Diskimage on a Par...

...e looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

Hi there, I've installed a Qlogic HBA in a 4.8-STABLE machine and I'm able to present LUNs to this machine from an HDS array and use them. That all works perfectly. However, the only time I pick up new LUNs is on a reboot. Seems like I should be able to rescan the fabric and pick up new LUNs, but there doesn't seem to be a way to do this. I tried camcontrol rescan, but that

Hi, I''m on a HP DL365, amd64, running SLES10sp1, but with kernel and xen of SLES10sp2, therefore using Xen 3.2. The domU shall be a Windows HVM guest. I want use the Qlogic SAN card in a domU. I''m following these instructions: http://www.novell.com/communities/node/2880/assign-dedicated-network-card-or-pci-device-xen-virtual-machine well, there is written that this only

I'm trying to run Samba on a gigabit network. On the server side I've got Samba 2.2.1 running on an sgi Origin200 with a gigabit ethernet card plugged into a gigabit switch, and the files are being served off a fibrechannel raid array. On the client side I have a windows 2k box with a gigabit card plugged into the same switch. Both machines and the switch claim that everything is running at 1Gb/s, yet file transfere doesn't seem any faster than with fast ethernet. Is samba simply not able to serve up files...

Hi, We've got a setup here with a samba server in front of a fibrechannel array. It's a pretty vanilla samba setup exporting an xfs filesystem. The box is an opteron 265 with 4G RAM and a QLogic QLA2312 HBA running SLES9. We can dd an 8G file to a share from a windows workstation in just over 2 minutes (about 65MB/s) and dd back in about 4 minutes. Local disk perf...

Hi All, I''ve been trying to get a bit of a grip on disk i/o for our Xen set- up. We''re dealing with server workloads that can, at unexpected times, become seriously io-bound, up to the point that a single guest can cannibalize the available throughput of the fibrechannel array. Since we''re dealing with a shared medium and multiple Xen hosts, I''m looking for a way in to put an upper cap on the number of i/o operations individual guests can perform. Although this is not entirely scientific, it would allow an informed administrator to limit...

Hi all, yesterday we had a drive failure on a fc-al jbod with 14 drives. Suddenly the zpool using that jbod stopped to respond to I/O requests and we get tons of the following messages on /var/adm/messages: Sep 3 15:20:10 fb2 scsi: [ID 107833 kern.warning] WARNING: /scsi_vhci/disk at g20000004cfd81b9f (sd52): Sep 3 15:20:10 fb2 SCSI transport failed: reason ''timeout'':

hi list, i have a little problem with 2-node RAC using OCFS. the application running on this cluster does heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel. the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000 while %util=100% (device was saturated) from kernel's POV. i did some benchmarking with Bonnie (http://www.textuality.com/bonnie/): # ./Bonnie -d /tmp/ocfstest/ -s 1024 -m bn1r...

Hello, I have a 1.3TB ext3 filesystem that has been in service for about 3 months. About 6 days ago the Emulex fibrechannel controller logged a SCSI error and the filesystem changed to RO. It appears that the filesystem instantly changes to RO and prevents the journal from working, therefore invalidating the filesystem. The filesystem was unmounted and a remount was attempted. The mount failed due to errors and an fs...

Hello folks, I have a Xen server running on Centos 6.2 with 3.6.6-1.el6xen.x86_64 as the Dom0 kernel, and i have dedicted 2 CPUs and 4G ram for the Dom0.I have close to 4-5 Virtual machines running on the Xen server. The problem is that for some reason,carrying outany CPU/Disk intensive task on the Dom0 seems to be affecting the DomUs adversly.For ex.i noticed that my Domus become extremly

...plied the patch to source/locking/shmem_sysv.c that Jeremy Allison has suggested for the other problems, and, well, it works now. I don't know what patches might have been applied to the machine since Friday - it's up and down like a yo-yo thanks to what looks like a disagreement with some fibrechannel discs. They added to the /etc/system file set lwp_default_stksize=0x4000 and, all that it's worth, uname -a gives SunOS odyssey 5.6 Generic_105181-14 sun4u sparc SUNW,Ultra-Enterprise.

Hi all, As the resident Linux guru, I've just been tasked with costing a webmail setup for about 600 000 users. They each have 10MiB (small, I know) mailboxes. The current setup has about 40 million web page accesses per month. Has anyone here any experience with this kind of thing? If so, any pointers as to software and hardware used, and any other advice would be appreciated. TIA --

Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look
