Yes, the clients are doing lots of creates. But my question is, if this is a memory leak, why does ocfs2 eat up the memory as soon as the clients start accessing the filesystem. Within about 5-10 minutes all physical RAM is consumed but then the memory consumption stops. It does not go into swap. Do you happen to know what version of ocfs2 has the fix? If it was a leak would the process not be

Hi Guys, My users are reporting some issues with memory on our lustre 1.8.1 clients. It looks like when they submit a single job at a time the run time was about 4.5 minutes. However, when they ran multiple jobs (10 or less) on a client with 192GB of memory on a single node the run time for each job was exceeding 3-4X the run time for the single process. They also noticed that the swap space

Under both XEN 3.0.4 (2.6.16.33) and XEN 3.1 (2.6.18), I can make the OOM killer appear in dom0 of my server by doing heavy I/O from within a VM. If I start 5 VMs on the same server, each VM doing constant I/O over its boot disk (read/write a 2GB file), after about 30 minutes the OOM killer appears in dom0 and starts killing processes. This was observed using 256MB in dom0. If I bump the memory in

Starting with 3.7 rc1, my workstation seems to loose ram. Up until (and including) 3.6, used-(buffers+cached) was roughly the same as sum(rss) (taking shared into account). Now there is an approx 6G gap. When the box first starts, it is clearly less swappy than with <= 3.6; I can''t tell whether that is related. The reduced swappiness persists. It seems to get worse when I update

I'm currently hacking on CTDB's IP takeover/failover code. For Samba 4.6, I would like to rationalise the IP takeover-related tunable parameters. I would like to know if there are any users who set the values of these tunables to non-default values. The tunables in question are: DisableIPFailover Default: 0 When set to non-zero, ctdb will not perform failover or

Hi Wei, I ran into the following problem when trying to boot another guest after less than a day of uptime. (the system started 15 guests at boot already which went fine). dom0 is allocated a fixed 1536M. Both host as pv guests run the same kernel, some hvm''s run a slightly older kernel (3.9 f.e.) The are quite some granttable messages in xl dmesg, i also included these and a

I can't resist. Read the thread that was pointed to on lkml. ROTFLMAO. *Real* UNIX addressed these problems long ago. I guess the "Gurus" suffer from NIH (Not Invented Here) syndrome. Given a "general purpose" system, tunability is a must. UNIX, as delivered by USL in such examples as Sys V, had tunables that let admins tune to their needs. A single "swappiness"

Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel

I have committed a fix for the panic that happened with the da(4) or cd(4) drivers configured and INVARIANTS turned on. Let me know if there are any problems/comments/questions.

OK, I've figured it out: In the dovecot profile for apparmor the sieve directory is not confgured. I solved it this way: To configure only one directory in the apparmor profile, I placed the active-script link inside the .sieve directory. Keeping the scripts separate in a store subdirectory, like this: In /etc/dovecot/conf.d/90-sieve.conf : sieve =

I would appreciate if somebody can clarify a few points. I am doing some random WRITES (100% writes, 100% random) testing and observe that ARC grows way beyond the "hard" limit during the test. The hard limit is set 512 MB via /etc/system and I see the size going up to 1 GB - how come is it happening? mdb''s ::memstat reports 1.5 GB used - does this include ARC as well or is

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

Changes in CTDB 2.5 =================== User-visible changes -------------------- * The default location of the ctdbd socket is now: /var/run/ctdb/ctdbd.socket If you currently set CTDB_SOCKET in configuration then unsetting it will probably do what you want. * The default location of CTDB TDB databases is now: /var/lib/ctdb If you only set CTDB_DBDIR (to the old default of
