Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

Hi all. I have problem with performance ocfs2. I just instaled ocfs2 1.4.1 in 2 nodes cluster. I use ocfs2 in mail server. This system has large amount of small files about 50kB. Ocfs2 is formated: >> mkfs.ocfs2 -T mail -N 2 /dev/sdb1 mkfs.ocfs2 1.4.1 Cluster stack: classic o2cb Overwriting existing ocfs2 partition. Proceed (y/N): y Filesystem Type of mail Filesystem label=

Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the

Hi people... Here we use Xen 4 with Debian Lenny... We''re using kernel 2.6.31.13 pvops... As a storage system, we use AoE devices... So, we installed VM''s on AoE partition... The "NAS" server is a Intel based baremetal with SATA hard disc... However, sometime I feeling that VM''s is so slow... Also, all VM has GPLPV drivers installed... So, I am thing about

Hi, I'm unable to get Kerberos4 authentication working with openssh-3.4p1. I'm getting a message that privsep is not available on my platform (Irix 6.5.15) and another message stating that compression and privsep are mutually exclusive. But, ssh decided to turn off compression, I think because of servconf.c. I think it would be more usefull to have compression enabled and disable privsep

Well, you are the second person who has complained about the performance of OCFS with the PERC controller. Best option would be to contact DELL. We are in contact with them... as in, they inform us of any issues they have with linux/ocfs on their hardware. As we do not have this particular hardware inhouse, all we can only speculate as to what the issue is. Things to look for ==> output

I have multiple puppetdb severs pointed at the same database.

Hi, I've reported this problem a month ago on this list, and probably no-one is interested? Binaries were configured with krb4 and afs enabled. However, only the second crash seems to be related to krb4. Any thoughts? I had to add one line to includes.h: #include <sys/types.h> #include <sys/socket.h> #include <sys/ioctl.h> +#include <sys/ioccom.h> #include

Does "bwlimit" option really work on rsync locally? We have one type of harddisk and want to slow down rsync I/O on disk because I don't want the disk head gets too hot. While I'm trying to use --bwlimit option, it looks the rsync speed was slowed down, but iostat is not improved at all. In both case the block written speed is increased by the same amount. How could I really

Hi All. Attached is a patch that implements password expiry with PAM and privsep. It works by passing a descriptor to the tty to the monitor, which sets up a child with that tty as stdin/stdout/stderr, then runs chauthtok(). No setuid helpers. I used some parts of Michael Steffens' patch (bugid #423) to make it work on HP-UX. It's still rough but it works. Tested on Solaris 8 and

Based on Rich's review of my v1 that touched only cache.c, I have now tried to bring all three filters with alignment rounding in line with one another. There is definitely room for future improvements once we teach nbdkit to let filters and plugins advertise block sizes, but I'm hoping to get NBD_CMD_CACHE implemented first.

Although the time spent in memcpy/memset probably pales in comparison to time spent in socket I/O, it's still worth worth reducing the number of times we have to utilize a bounce buffer when we already have aligned data.

I'm trying to replicate the features of the qemu curl plugin in nbdkit's curl plugin, in order that we can use nbdkit in virt-v2v to access VMware servers. I've implemented everything else so far [not posted yet] except for readahead. To my surprise actually, qemu's curl driver implements readahead itself. I thought it was a curl feature. I'm not completely clear _how_ it

Hi, I just tried the 2.6.22-r1 candidate to test whether some bug I have hit in the past still exists. I did use 2.6.20.6 so far. So, I have cleanly rebooted to use the new kernel, after the machine came up I tried to mess with the bug, and had to reboot again to play with kernel commandline parameters. Unfortunately, on the next reboot fsck was schedules on my filesystem after 38 clean

I do have a question about whether patch 2 is right, or whether I've exposed a bigger problem in the truncate (and possibly other) filter, but the rest seem fairly straightforward.

Hello, We are planning to moving most of our servers to ESX but before buying our SAN, we want to do some I/O stats to see if iSCSI is enough or if we have to go with FC. So I found a plugin for Nagios that can log I/O stats with iostat. So far it's fine with single disk/one partition servers, but on our Oracle Database 10g server, we have two drives in RAID 1 (/dev/sda) and 4 other
