Hello, I am planning on deploying a few more clients in my lustre environment and was wondering which client version to install. I know it is okay to run a newer client version than your lustre server for upgrade purposes. However, would it be okay to be in this state for a longer period of time (for the life of this filesystem)? My lustre server is currently running 1.8.1.1 on RHEL 5.3 and I

Hello All, I''d like to announce the creation of a new lustre-community at lists.lustre.org mailing list.

Just checking to be sure this isn''t a known bug or problem. I couldn''t find a bz for this, but it would appear that tunefs.lustre --print fails on a lustre mdt or ost device if mounted with mmp. Is this expected behavior? TIA mds1-gps:~ # tunefs.lustre --print /dev/mapper/mdt1 checking for existing Lustre data: not found tunefs.lustre FATAL: Device /dev/mapper/mdt1 has not

Will lustre-1.5.95 build with 2.6.18-vanilla kernel? Which_patch doesn''t contain this kernel but I could see them in the series files. Do somebody have experience in building the same? I tried to do it but lot of errors after applying the patches in 2.6.18-vanilla series. Thanks, Venkat

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

Hi there, When Lustre is configured in an environment where there are multiple paths to the same destination of the same length (i.e. two paths, each one hop away), which path(s) will be used for sending and receiving data? I have my cluster configured with two OSTs with two GigE NICs in each. I am seeing identical performance metrics when I use LACP to aggregate, and when I use two separate

As any of you using version 1.6 of Lustre knows, Lustre servers can now be started simply my mounting the devices it is using. Even an /etc/fstab entry can be used if you can have the mount delayed until the network is started. Given this change, you have also notices that we have eliminated the initscript for Lustre that used to exist for releases prior to 1.6. I''d like to take a

In hopes of improving the quality, coverage, and currency of the Lustre User Manual, I''m putting out a call to the Lustre community for contributors to this important resource. The user manual is especially important for new users to Lustre, but has fallen into some disrepair now that there is no longer a dedicated documentation writer for it. As well, there are many sections of the

Hi, has anyone tried to compile the lustre patchless client on a debian linux for arm architecture? Could be possible to do? Thanks in advance.

Since in Linux we are mostly a debian shop we''d like to stick with debian for our calculation nodes if possible. So I wanted to ask the lustre 2.2 instructions for Debian are they more or less relevant to lustre 2.4/2.5 or am I going headlong into a tall brick wall. Also are newer clients backwards compatible with older server software? I am currently just setting up a demo environment
