Hi, First of all, I'm new to ocfs2 and drbd. I set up two identical servers (Athlon64, 1GB RAM, GB-Ethernet) with Debian Etch, compiled my own kernel (2.6.16.20), then compiled the drbd-modules and ocfs (modules and tools) from source. The process of getting everything up and running was very easy. I have one big 140GB partition that is synced with drbd (in c-mode) and has an ocfs2

Hello, I''m running into some trouble with what appear on the surface to be OOM issues in Dom0, but I''m not seeing any other evidence. This typically happens during periods of high I/O, and has occurred during RAID initial sync, and mkfs.ext4ing (as a test, no intention to keep ext4 on this array). I''ve found some older posts citing very similar circumstances, however

I have continous oom&panic situation unresolved. I am not sure system fills up all the ram (36GB). Why this system triggered this oom situation? Is it about some other memory? highmem? lowmem? stack size?

Not sure if it''s anything interesting - I had the following entry in dmesg a few days ago, on a server with 32 GB RAM. The system is still working fine.

Dear list, I am seeing an error across multiple machines during heavy I/O, either disk or network. The VMs are on different Intel CPUs (Core 2 Quad, Core i5, Xeon) with varying boards (Abit, Asus, Supermicro). Machines that get this error are running either BackupPC, Zabbix (MySQL) or SABNZBd. I can also reproduce the error on the Supermicros with a looped wget of an ubuntu ISO as they are

hi xen 4.0.1 w/2.6.32.41 Last week dom0 experienced an hard crash and box need to be restarted manually (despite kernel.panic=20). Serial console was not setup, only netconsole. No relevant entries through netconsole, but analyzing logs I see some crashes twenty minutes before fatal hang.

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

Hi All, Running into temporary pauses in our VMs which correspond to these errors in dmesg on the dom0: [1721485.352560] SLUB: Unable to allocate memory on node -1 (gfp=0x20) [1721485.352563] cache: kmalloc-2048, object size: 2048, buffer size: 2048, default order: 3, min order: 0 [1721485.352566] node 0: slabs: 81, objs: 1296, free: 0 [1721485.352576] swapper: page allocation failure:

Hi Konrad, In one of my domU''s to which I pci passthrough USB cards with a videograbber connected to it, the videocapture bails out after running for quite some time with the stacktrace below. I guess i''m interpreting the mem-info below wrong, but i fail to see why it can''t allocate those 185088 bytes. Could you shed some light ? it''s probably the coherent

Dear all, I have sent this problem earlier but maybe its not detail, here I try to write more detail. I hope anybody can help me to point out the problem. First of all I used Ubuntu 12.04 x64 both for domain0 and domainU with modification to run under xen hypervisor and work with remus. I follow and configured the remus with this notes

Dear all, I have installed DRBD 8.3.11 compiled from sources. However the backend block will freeze if there is high IO load. I use Remus to support high availability and checkpointing is controlled by remus for each 400ms. If I check the Iostat I got the idle CPU will decreasing extremely each checkpointing and when its reach 0% of idle cpu the local backing device will freeze and damage the

Hello List, i am running Debian Squeeze and i installed DRBD, 3.2.0-0.bpo.4-amd64 and Xen4.0 from the Backports. Sometimes i get such ugly Kernel message: [257318.441757] BUG: unable to handle kernel paging request at ffff880025f19000 Log: [256820.643918] xen-blkback:ring-ref 772, event-channel 16, protocol 1 (x86_64-abi) [256830.802492] vif86.0: no IPv6 routers present [256835.674481]

By crash I mean the gnome screen was blown away, replaced by a black screen with white log lines. That seems to happen every time dom0 uses a large amount of memory. After setting

Hi, I would normally post this to the drbd list but it so low traffic/low volume (plus Austria might be asleep right now) I figured i'd ask someone here in case they have gotten drbd working on centos. Right now my system says i'm only the 971st person to even install it... It's been out for years, so likely this just means version 8. But you'll only see a couple of posts

Hello On my HP Compaq dc5800 with Ubuntu 13.04 and their 3.8.0-19-lowlatency kernel, I''ve got quite some kernel traces in the syslog. You can find them below or at http://pastebin.com/bLXPBX67 (to avoid line breaks…). These kernel traces all begin with: WARNING: at fs/btrfs/free-space-cache.c:921 __btrfs_write_out_cache+0x6b9/0x9a0 [btrfs]() Most of the time, it starts with: Call

Hi all, I don''t know if my question doesn''t related to xen at all, how ever I am trying to use DRBD as my disk replication when I ran Remus. However when I run remus sometimes my Dom-U will be freezing. I see the log file and it seem caused by drbd frozen : 875.616068] block drbd1: Local backing block device frozen?
