Hi all, Recently I have acquired a supermicro e200-8d micro server to use it as my homelab. It is equipped with two ssd disks. My idea is to install several kvm guests on it, but I have some doubts about what type of filesystem (ext4 or xfs?) or block to use (lvm). Recommendations? Do I need to accomplish some type of running if I choose to us...

...da (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we c...

...5.2 (but the problem was already present in 5.0 as well), and running the latest production version of VMWare server 1.0.7 (but when running 1.0.5 the problem was there too). One host as an adaptec 2820 with 4 SATA drives, and uses the aacraid driver. Another host is a proliant with a smart array E200, battery backed cache of 128 MB using the cciss driver. Filesystem is ext3 on both hosts. When measuring the write performance, I try to avoid measuring the use the buffer cache like this, writing a 4.2gb file: $ sync; time sh -c 'dd if=/dev/zero of=large bs=8k count=500k; sync' (Ign...

Hi all, I discovered lately that two of my XEN servers suffer from a really bad disk throughput - in domU as well as in dom0. All of them run Debian/Etch, Kernel 2.6.18-6-xen (orig. Debian) with XEN 3.2 (backported). The software versions seem to be ok for most machines: Lenovo A57 with S-ATA and (E8200, VT enabled): up to 90MB/s Shuttle, FB61 based, ATA-Disk (Celeron, no VT): up to

We just installed a new cluster with 6 HP DL380g5, dual single port Qlogic 24xx HBAs connected via two HP 4/16 Storageworks switches to a 3Par S400. We are using the 3Par recommended config for the Qlogic driver and device-mapper-multipath giving us 4 paths to the SAN. We do see some SCSI errors where DM-MP is failing a path after get a 0x2000 error from the SAN controller, but the path gets puts

Hi, we are currently working on getting windows working on your xen servers. but we are facing a severe problem where dom0 and all domus hang for 1-5 seconds from time to time. we think it is probably because of disk i/o, because top sometimes says 100% wa (waiting on io) during the hang. dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7. should we give dom0 more than once

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel:
