Hi, I have setup about a year ago a BTRFS RAID 1 filesystem on two 2TB Western Digital WD20EARS hard drives and I have created subvolumes that I mount regularly as I need them. I put mostly music, videos and various files on them as well as some Git bare repositories for my work files but for the last couple of weeks, there seems to be some activity happening on the drives for a few minutes and

The softlockup watchdog is currently a nuisance in a virtual machine, since the whole system could have the CPU stolen from it for a long period of time. While it would be unlikely for a guest domain to be denied timer interrupts for over 10s, it could happen and any softlockup message would be completely spurious. Earlier I proposed that sched_clock() return time in unstolen nanoseconds, which

Here's couple of patches to improve the softlockup watchdog. The first changes the softlockup timer from using jiffies to sched_clock() as a timebase. Xen and VMI implement sched_clock() as counting unstolen time, so time stolen by the hypervisor won't cause the watchdog to bite. The second adds per-cpu enable flags for the watchdog timer. This allows the timer to be disabled when the

I''m trying to do nested XEN to give some of my colleagues a play area to work in, and it seems to work - but not quite. I can build the nested environment (using OVM, and I have to step back to OVM3.2.2 to allow me to do PCI passthrough), but as soon as I start up a VM with a phys device passed through, the first layer loses all connectivity to the SAN. Setup: * 2 UCS

Hi, I'm cross compiling win R in a linux Ubuntu Edgy and I'm getting an error with the utils package. Sys.setenv exists on my R 2.5.0 ... I'm using the tools provided for R250 in http://www.stats.ox.ac.uk/pub/Rtools/i586-cross-tools.tar.bz2 Any ideas ?

Hi Ingo, This series of patches implements a number of improvements to the softlockup watchdog and its users. They are: 1. Make the watchdog ignore stolen time When running under a hypervisor, the kernel may lose an arbitrary amount of time as "stolen time". This may cause the softlockup watchdog to trigger spruiously. Xen and VMI implement sched_clock() as measuring unstolen time,

Hello all. What we have: SL6 - kernel 2.6.32-131.2.1.el6.x86_64 btrfs on mdadm RAID5 with 8 HDD - 27T partition. I see this at top: 1182 root 20 0 0 0 0 R 100.0 0.0 16:39.73 [btrfs-delalloc-] And LA is grow. What is this and how can I fix it? -- Best regards, Proskurin Kirill -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of

While untar''ing an image to an sd card via a reader, I got the following bug. The system also has a btrfs root, and a whole swath of processes went into uninterruptable sleep. I was able to poke around via ssh and sysrq, and already had netconsole set up to capture the bug. Root fs is on /dev/sdi1, and /dev/sdj2 is the card reader which was the target of the untar.

Hi all, Last week we had 2 times an "uncorrectable ecc memory error" crash on our server on the same memory module. After removing the faulty module and restarting the server, everything was working again. However, yesterday we had a soft lockup and had to restart the server again. No warning or ecc error this time. Everything is working now, but we want to avoid this in the future

Thanks Cristoph, I have that code in my backend, but unless I do the following, the registers are never considered 'live' into the call. / Handle a function call let isCall = 1, Defs = [ R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R23, R24, R25, R26, R27, R28, R29, R30, R31, R32, R33, R34, R35, R36, R37, R38, R39, R40, R41,

Stamp softlockup thread earlier before do_timer, because the latter is the one to actually trigger lock warning for long-time offline. Or else, I obserevd softlockup warning easily at manual vcpu hot-remove/plug, or when suspend cancel into old context. One point here is to cover both stolen and blocked time to compare with offline threshold. vcpu hotplug falls into ''stolen''

Hello, I habe the problems described in here https://btrfs.wiki.kernel.org/index.php/Gotchas: Files with a lot of random writes can become heavily fragmented (10000+ extents) causing trashing on HDDs and excessive multi-second spikes of CPU load on systems with an SSD or large amount a RAM. On servers and workstations this affects databases and virtual machine images. The nodatacow mount option

I'm very new to R, trying to learn it. I started with R 2.4, but I have since upgraded to 2.5.0, on WindowsXP. I understand that 2.5.1 is now available. Last night in the course of things I loaded libraries "coin" and "survival". I received warning messages that they had been built under version 2.5.1. However, as far as I could tell, they worked OK. But this brought
