I'm trying to get some data about the relative distribution of MDS operations in the wild, and I'd be grateful if some people with production filesystems that have been running for at least a week could collect some simple stats and email them to me. They can be collected by any regular user on the MDS node:
lctl get_param mds.*.stats | egrep "open|close|rename|link|attr|sync"
It would be useful to also include "lfs df" and "lfs df -i" information, as well as a brief description of what the filesystem is used for (scratch, home, project, archive, etc).
As a reminder, I'm also interested if some Lustre admins could run the "fsstats" tool from http://www.pdsi-scidac.org/fsstats/ and send me the output. Sending the output to PDSI via their submission form may also produce some positive results.
http://www.pdsi-scidac.org/fsstats/files/fsstats-1.4.5.tar.gz
Thanks in advance for any data. I've set replies to go only to lustre-devel, to avoid clogging the larger readership of lustre-discuss, but it may be useful for others to have this in a list archive and/or searchable via Google in the future so I don't necessarily want to keep it all to myself.
Cheers, Andreas

Subject: [Lustre-devel] Research on filesystem metadata operation distribution
I'm trying to get some data about the relative distribution of MDS operations in the wild, and I'd be grateful if some people with production filesystems that have been running for at least a week could collect some simple stats and email them to me. They can be collected by any regular user on the MDS node:
lctl get_param mds.*.stats | egrep "open|close|rename|link|attr|sync"
It would be useful to also include "lfs df" and "lfs df -i" information, as well as a brief description of what the filesystem is used for (scratch, home, project, archive, etc).
As a reminder, I'm also interested if some Lustre admins could run the "fsstats" tool from http://www.pdsi-scidac.org/fsstats/ and send me the output. Sending the output to PDSI via their submission form may also produce some positive results.
http://www.pdsi-scidac.org/fsstats/files/fsstats-1.4.5.tar.gz
Thanks in advance for any data. I've set replies to go only to lustre-devel, to avoid clogging the larger readership of lustre-discuss, but it may be useful for others to have this in a list archive and/or searchable via Google in the future so I don't necessarily want to keep it all to myself.
Cheers, Andreas

The filesystem lustre_0 (lustre_1 is used for small tests) is used for
storage of data from the LHC at CERN. We are a WLCG Tier-2 site and uses
the "StoRM" SRM implementation.
The filesystem is mostly used for storage of datasets around 2Gig in
size, but the software area is also on Lustre (except for our main
customer, ATLAS, where the mds was a bottleneck, so we now use the CVMFS
caching filesystem for them).
The filesystem has been up 18 days, but under somewhat reduced load from
normal due to problems with our airconditioning.

Hmm - also 'uptime' would really be nice to have with these so we could estimate rough rates...

Attached is the stats from the cosmology cluster lustre file system.
We use this filesystem as a general purpose storage system to store the outputs, binaries and code.
The storage space is not backed up and users have to write the files manually to the tape if needed.

At GSI, we have
lctl get_param mds.*.stats | egrep "open|close|rename|link|attr|sync"
open 10302752480 samples [reqs]
close 528292519 samples [reqs]
unlink 22292174 samples [reqs]
rename 542512 samples [reqs]
getxattr 408511496 samples [reqs]
setxattr 838368 samples [reqs]
setattr 27097846 samples [reqs]
getattr 738233548 samples [reqs]
Output of 'lfs df' is attached.
The filesystem is used for storing HEP data from theory calculations,
simulations and HEP experimental data for use in analysis. People also
use it as a software repository, to compile their programs (ouch) and as
a general purpose distributed file system (a certain sysadmin is known
to store his music files there).

Thomas

While it wasn't my original goal in asking for this data, a question I've been asking all of the sites that have filesystems with OSTs of different sizes is whether they use (and/or continue to use) an external process for balancing the space used on the OSTs (e.g. migrating of files, or marking OSTs inactive on the MDS once they have reached some threshold of space usage), or if the existing space balancing mechanism in the MDS was able to get this relatively uniform space utilization?
> The filesystem is used for storing HEP data from theory calculations, simulations and HEP experimental data for use in analysis. People also use it as a software repository, to compile their programs (ouch) and as a general purpose distributed file system (a certain sysadmin is known to store his music files there).
