similar to: CentOS 6 kvm disk write performance

Will Dovecot be negatively impacted if I change my XFS mount options to noatime,nodiratime? Thanks. -- Stan

by using ms-word2003 I'm not able to write on my ntfs disk. out of wine I've no problem, so rights-setting seems to be OK. Thanks for help

After a successful using a wine in my comp for a couple days, now, suddenly without any big change in system, I cannot start any exe, even core application as winecfg. Code: >winecfg err:module:attach_process_dlls "gdi32.dll" failed to initialize, aborting err:module:LdrInitializeThunk Main exe initialization for L"C:\\windows\\system32\\winecfg.exe" failed, status

On a 32bit Windows 2008 Server guest VM on a CentOS 5 host, iometer reported a disk write speed of 37MB/s The same VM on a CentOS 6 host reported 0.3MB/s. i.e. The VM was unusable. Write performance in a CentOS 6 VM was also much worse, but it was usable. (See http://lists.centos.org/pipermail/centos-virt/2012-August/002961.html) With iometer still running in the guest, I installed tuned on

I've had the chance to use a testsystem here and couldn't resist running a few benchmark programs on them: bonnie++, tiobench, dbench and a few generic ones (cp/rm/tar/etc...) on ext{234}, btrfs, jfs, ufs, xfs, zfs. All with standard mkfs/mount options and +noatime for all of them. Here are the results, no graphs - sorry: http://nerdbynature.de/benchmarks/v40z/2009-12-22/ Reiserfs

Hi, I am running C6.5 64bit on an USB stick connected to a HP DL360G7; It is usually an ESXi host but eg for firmware updates (not available on SPP) I use this local installation. Problem are the lags and unresponsiveness we are seeing for example when running yum update in the installation phase. The whole system stalls but there is no io in vmstat. From what google tells us, this is a

I am trying to install 6.2 on a machine. I am using PXE as I have done so a number of times. My hard disk is being detected as sdb and not sda. My kickstart config is wanting it at sda. There are no other disks in the unit. It has and SD slot and an esata although BIOS does not appear to have a disable for either of those devices. Is there anyway to "force" the disk to sda ? or find

Nikita, Please take a look at the attached patch. I have rewritten it a little, and only lightly tested it. Rich.

Yes, multiple imap servers using one shared nfs storage. With the same config on 2.2.13 the public interface traffic was similar to the storage interface, around 100 mbps. After we switch to 2.2.27 the storage interface traffic jumped 10 times while the public interface stayed the same. This make us thinking that something is wrong and each time a user logs in the whole Inbox content is read

Hello everyone, Btrfs v0.10 is now available for download from: http://oss.oracle.com/projects/btrfs/ Btrfs is still in an early alpha state, and the disk format is not finalized. v0.10 introduces a new disk format, and is not compatible with v0.9.

I do not mean to be argumentative, but I have to admit a little frustration with Gluster. I know an enormous emount of effort has gone into this product, and I just can't believe that with all the effort behind it and so many people using it, it could be so fragile. So here goes. Perhaps someone here can point to the error of my ways. I really want this to work because it would be ideal

Hi, I'm running 3 Dovecot director and 6 Dovecot backend on CentOS 6 and Dovecot 2.3.10, with Maildir shared on NFSv3 (on NetApp).
