Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it

Hi all, Does any one know of a how to for creating raid 1 + LVMs during install for Centos 6? Do I create the physical LVM first and then raid or vise versa? Its seems diff then doing it for Centos 5. - aurf

Hi all, I've got a Centos 5.1 kickstart that I must continue to use. How can I update the kick start image so that it recognizes Intel gigabit 82576 nic? BTW, I compiled the driver I need and have this igb.ko file. How do I incorporate that into my initrd.img file that I see on the kickstart CD that is probably my kickstart boot OS. Thank you very much in advance. aurf -

Hi, I've been using qemu-img resize for a few days now, seems fine. But if I du the VMs image file, it still shows the size before resizing. Inside that VM, the new size shows correctly. Is qemu-img resize the right tool for this? Once I qemu-img resize, I then use various fdisk/ LVM tools, etc... to resize within the VM just incase you all were wondering. - aurf

Hi all, Don't mean to double post as I sent this to the general Centos list. But, does any one have 802.3ad (mode 4) working on there Centos6 KVM setup? This would be a bridge+bond setup of course. If not possible, would I still bond the interfaces on the switch and then bond them in the guest rather then from within the hypervisor? - aurf

Hi, I'm VNCing into my KVM server and opening virt-manager. When trying to manage a newly created guest, I'm finding the mouse pointer stays on the outside of its virtual machine window. Any insight as to why its tracking so oddly? Thanks in advance, - aurf

Hi all, I've a particular host on my network that when I run; rexec -l username -p password remotehost command it just hangs.

Any ideas would be very appreciated. - aurf

Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

Hi all, Taken from this link; https://www.centos.org/modules/newbb/print.php?form=1&topic_id=34988&forum=55&order=ASC&start=0 Seems like I am having the same issue. I assigned my boot loader to be on /dev/md0 rather then the default of /dev/sda1 Does any one have insight to this? Thanks in advance. BTW, I have no swap partition and will do a swap file instead, easier to

Hi all, I never really paid attention to this but a file on an NFS mount is showing 64M in size, but when copying the file to a local drive, it shows 2.5MB in size. My NFS server is hardware Raided with a volume stripe size of 128K were the volume size is 20TB. My NFS clients are the same distro as the server being Centos. Is this due to my stripe size? Nuggets are appreciated. - aurf
