Hi all I have a remote server (i.e SSH access only) which was incorrectly partitioned and I urgently need to get it up and running. It's got a 500GB HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This is on LVM, btw.

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update". As far as I can tell the only three packages were updated Jul 24 16:37:49 Updated: php-common - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php-cli - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php - 5.1.6-20.el5_2.1.i386 But when I rebooted the Server one of my

Hi, I have CentOS 5.0 which use an old hard disk. And recently I found there are some bad sector on it ... I try to backup my data to other CentOS 5.0 box .... What I did is. I remove the old HD (with bad sector) and install it as a slave IDE on a working CentOS 5.0 ... I try to mount the old HD as /mnt/oldDisk but since it's a LVM, the "mount -t ext3" doesn't work. I'm

I'd like to automate the upgrade from CentOS 4.6 to 5.1 as much as possible. Since upgrades per se are not really recommended, I'm planning to do a kickstart installation. However, I want to leave one of the existing partitions (/scratch) untouched during the installation. Here is my current layout (LogVol00 is swap so not shown in the df output below): # df -hl

I have a centos 5.6 server that has xen domUs installed on their on logical volumes. These logical volumes contain their own volume groups and again their own logical volumes. I want to access the domU logical volumes and tried this: [root at kr ~]# fdisk -l /dev/VolGroup00/LogVol02 Disk /dev/VolGroup00/LogVol02: 274.8 GB, 274877906944 bytes 255 heads, 63 sectors/track, 33418 cylinders Units =

Hi list. I am dealing with DRBD (+GFS as its DLM). GFS configuration needs a CLVMD configuration. So, after syncronized my (two) /dev/drbd0 block devices, I start the clvmd service and try to create a clustered logical volume. I get this: On "alice": [root at alice ~]# pvcreate /dev/drbd0 Physical volume "/dev/drbd0" successfully created [root at alice ~]# vgcreate

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

I have a vanilla CentOS 5.9 system. I have a pair of 2Tb sata drives with a RAID 1 array on them. This array contains an LVM physical volume. I have added these two drives to my system and now need to access the volume group on this physical volume. This volume group, vg0, contains 10 ext3 file systems and I need to get the data from them. What do I know: [root at mickey ~]# pvscan PV

After upgrading my HD, I am now wishing I left some space for doing snapshots. Is there a way to free up some space so I can get some free PE? Right now I have this: # vgdisplay --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 7 VG Access read/write VG Status resizable

Does anybody here have any idea how to make an exact copy of a drive that has LVM partitions? I'm having trouble using dd to do this for an EL5 server. We're trying to diagnose a software problem of some kind and would like an exact, perfect copy of the software running so that we can see exactly what the problem is without disturbing our production copy. It's been admin practice

Hey Roger, I am seeing this weird behavior when using #linux-next + stable/for-jens-3.8 tree. Basically I can do ''pvscan'' on xvd* disk and quite often I get checksum errors: # pvscan /dev/xvdf PV /dev/xvdf2 VG VolGroup00 lvm2 [18.88 GiB / 0 free] PV /dev/dm-14 VG vg_x86_64-pvhvm lvm2 [4.00 GiB / 68.00 MiB free] PV /dev/dm-12 VG vg_i386-pvhvm lvm2

Basically the issue comes down to my Volume Groups not being found by this initrd, causing good ole kernel panic. initrd-2.6.12.6-xen3_12.1_rhel4.1.img [root@xen01 lvm]# uname -a Linux xen01.inside.***.com 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:13:01 EST 2006 i686 i686 i386 GNU/Linux [root@xen01 lvm]# cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 2) Everything

Could someone tell me what could be causing this failure on my system and a way to get around/fix it? Your help is very much appreciated. I'd just finished running lvm lvextend.

Hi guys, sorry if this is trivial, but I have been googling a couple days and already compromised a test disk trying to figure this out, so I thought it is time to ask for some advice. I have a disk that comes from a clean and working CentOS4.2 install, and I am trying to use an external usb to ide converter to mount it on another workstation with CentOS4.2. I am trying this to better

Hi I have setup software RAID two years ago using FC3 using the graphical installer (RAID1). In the mean time I installed CENTOS4.5 and everything is running fine. At least that was my perception. It now turns out that raid is not working and that LVS just finds 4 partitions from four disks and that's it.: /dev/sda2 VolGroup00 lvm2 a- 94.88G 0 /dev/sdb1 VolGroup00 lvm2 a-
