similar to: bad 1.6.3 striped write performance

Hi all, anybody knows what ptlrpcd is good for, what it might be doing? I''ve seen it eating 100% CPU on OSS where I reformated an OST, but also in other circumstances. Regards, Thomas

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

Hi Everyone, git noob. simple question, how do i get a previous release from jeremy''s git repository? Right now, I can get the latest (2.6.32.9) by doing the following: git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen $ cd linux-2.6-xen $ git pull I tried doing a "git tag -l" when in linux-2.6-xen directory, but that did not print the tag

Anyone have any experience with MpiBlast and Lustre. We have MpiBlast-1.4.0-pio and lustre-1.6.3 and we are seeing some pretty poor performance with most of the mpiblast threads spending 20% to 50% of their time in disk wait. We have the genbank nt database split into 24 fragments (one for each of our OSTs, 3 per OSS). The individual fragments are not striped due to the

Hello, in preparation for CentOS 6.5 I was trying to build Lustre 1.8 client on CentOS 6.4 updated with 2.6.32-431 kernel.

Hello, Is there a way how to list all clones for given snapshot of a file- system ? e.g. I have the following snapshots: local/testfs at sunday local/testfs at monday local/testfs at tuesday and clone local/tuesday of local/testfs at tuesday. Now I''d like to get local/tuesday using local/testfs at tuesday as input. v.

The race condition is noticed between disk_add() and disk attributes, on virtio-blk hotplug. Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that point we haven't created the serial attribute file, therefore depending on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get created. As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk

Hi, Our lustre environment is: 2.6.9-55.0.9.EL_lustre.1.6.3smp I would like to change recovery timeout from default value 250s to something longer I tried example from manual: set_timeout <secs> Sets the timeout (obd_timeout) for a server to wait before failing recovery.
