How to bypass failed OST without blocking?
Hi I want my lustre do such things during OST failed: if some file has stripe data on th failed OST, any operation on the file will return IO error without blocking, and also at this moment I can create and read/write new file or read/write files which have no stripe data on the failed OST without blocking. What should I do ? How to configure? thanks! swin -------------- next part

Quota setup fails because of OST ordering
Hi all, after installing a Lustre test file system consisting of 34 OSTs, I encountered a strange error when trying to set up quotas: lfs quotacheck gave me an "Input/Output error", while in /var/log/kern.log I found a Lustre error LustreError: 20807:0:(quota_check.c:227:lov_quota_check()) lov idx 32 inactive Indeed, in /proc/fs/lustre/lov/.../target_obd all 34 OSTs were listed

compiling tests/Embedding
I am compiling the Embedding examples in the tests directory and get an undefined reference. I include the make output as well as grep'd output of nm on libR.so and compiler and arch information. Do I have an improperly built R shared library or is there a problem with the Embedding tests or something else I am not seeing? Thanks for any help! George ost at

lctl deactivate questions
Hi; One of our OSTs filled up. Once we realized this, we executed lctl --device 9 deactivate on our fs''s combo MDS/MGS machine. We saw in the syslog that the OST in question was deactivated: Lustre: setting import ufhpc-OST0008_UUID INACTIVE by administrator request However, ''lfs df'' on the clients does not show that the OST is deactivated there, unless we *also*

Files written to an OST are corrupted
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

No space left on device on not full filesystem
Hello, We have running lustre 1.8.1 and have met "No space lest on device" error when uploading 500 Gb small files (less then 100 Kb each). The problem seems to depends on the number of files. If we remove one file, we can create one new file, even with Gb size; but if we haven''t remove something we can''t create even very little file, as an example using touch

How to remove OST permanently?
All, I''ve added a new 2.2 TB OST to my cluster easily enough, but this new disk array is meant to replace several smaller OSTs that I used to have of which were only 120 GB, 500 GB, and 700 GB. Adding an OST is easy, but how do I REMOVE the small OSTs that I no longer want to be part of my cluster? Is there a command to tell luster to move all the file stripes off one of the nodes?

OSTs inactive on one client (only)
Hi everyone, I have seen this question here before, but without a very satisfactory answer. One of our half a dozen clients has lost access to a set of OSTs: > lfs osts OBDS:: 0: lustre-OST0000_UUID ACTIVE 1: lustre-OST0001_UUID ACTIVE 2: lustre-OST0002_UUID INACTIVE 3: lustre-OST0003_UUID INACTIVE 4: lustre-OST0004_UUID INACTIVE 5: lustre-OST0005_UUID ACTIVE 6: lustre-OST0006_UUID ACTIVE

Adding OST to online Lustre with quota
Hello, we wounder whether is it possible to add OSTs to the Lustre with quota support without making it offline? We tried to do this but all quota information was lost. Despite the fact that OST was formatted with quota support we are receiving this error message: Lustre: 3743:0:(lproc_quota.c:447:lprocfs_quota_wr_type()) lustrefs-OST0016: quotaon failed because quota files

Balancing I/O Load
We are seeing some disturbing (probably due to our ignorance) behavior from lustre 1.6.3 right now. We have 8 OSSs with 3 OSTs per OSS (24 physical LUNs). We just created a brand new lustre file system across this configuration using the default mkfs.lustre formatting options. We have this file system mounted across 400 clients. At the moment, we have 63 IOzone threads running

Unusual Block Allocations on OSTs
Hi, I see some unusual block allocations on my OSTs, and I was wondering if someone could explain to my why, and help me to fix a performance problem. In order to track down a performance issue, I ran the following test: - I reformatted my OSTS (I have 4 OSTs). - I created a 10G file on each OST. - I ran dumpe2fs to see if I had some unusual fragmentation going on. dumpe2fs shows

Getting a list of files on down OST
Hi Guys, I''m trying to figure out a way to get a list of files with objects present on an OST that is down. Normally one could do: lfs find -O <OST> dir but that is giving us Input/output errors (I assume because the OST is down). Is there a good way to get a list of objects (Maybe from the MDS?), what OSTs they are on, and correlate them with files? Thanks, Mark -- Mark

Lost folders after changing MDS
OK, so our old MDS had hardware issues so I configured a new MGS / MDS on a VM (this is a backup lustre filesystem and I wanted to separate the MGS / MDS from OSS of the previous), and then did this: For example: mount -t ldiskfs /dev/old /mnt/ost_old mount -t ldiskfs /dev/new /mnt/ost_new rsync -aSv /mnt/ost_old/ /mnt/ost_new # note trailing slash on ost_old/ If you are unable to connect both
