Dear All, I have one VG with one LV inside consist of four disk (and four PV) somehow the UUID is changed. I try to restore with the last known good configuration and use pvcreate --uuid xxx --restorefile xxx but I think when I first time do it I did use wrong UUID for two device. but haven't only using command above and haven't used vgcfgrestore. After carefully read the configuration,

I'm trying to extend a logical volume and I'm doing as follow: 1- Run `fdisk -l` command and this is the output: Disk /dev/sda: 85.9 GB, 85899345920 bytes 255 heads, 63 sectors/track, 10443 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier:

I've started updating systems to CentOS 7.6, and so far I have one failure. This system has two peculiarities which might have triggered the problem. The first is that one of the software RAID arrays on this system is degraded. While troubleshooting the problem, I saw similar error messages mentioned in bug reports indicating that sGNU/Linux ystems would not boot with degraded software

Hey guys, I need to use iostat to diagnose a disk latency problem we think we may be having. So if I have this disk partition: [root at uszmpdblp010la mysql]# df -h /mysql Filesystem Size Used Avail Use% Mounted on /dev/mapper/MysqlVG-MysqlVol 9.9G 1.1G 8.4G 11% /mysql And I want to correlate that to the output of fdisk -l, so that I can feed the disk

We are in the process of migrating several stand-alone server hosts onto a CentOS-6 kvm virtual host. We also use Webmin to administer our hosts. All of the guests, without exception, have been cloned brom a prototype guest using virt-manager. All of the additional VirtIO disks assigned to some of the guests have been added through virt-manager as well. Recently I have encountered a situation

Hi all, I had centos 5.9 installed with one of its volumes (non-root) on LVM: ... /dev/vgapps/lvapps /opt/apps ext3 defaults 1 2 ... Then installed centos 6.4 on this servers but without exporting this volume (I wanted to reuse it). After that instead importing it I did: # pvcreate /dev/sddlmac # vgcreate vgapps /dev/sddlmac And then realised that I should have

We add disks to an LSI raid array periodically to increase the amount of available space for business needs. It is understood that this process starts with metal, and has many layers that must each adjust to make use of the additional space. Each of these layers also says that it can do that 'online' without interruption or rebooting. But making it happen is not that easy. When the HW

Hi all! I've got a VM at work running C6 on HyperV (no, its not my fault, that's what the company uses. I'd rather gag myself than own one of th ose things.) I ran out of disk space in the VM, so the admin enlarged the virtual disk. but now I realize I don't know how to enlarge the partition and its filesystem. I'll be googling, but in case I miss it, it'd be great if

Dear John, I understand; I tried it in the hope that, I could activate the LV again with a new PV replacing the damaged one. But still I could not activate it.

Dear Chris, James, Valeri and all, Sorry to have not responded as I'm still on struggling with the recovery with no success. I've been trying to set up a new system with the exact same scenario (4 2TB hard drives and remove the 3rd one afterwards). I still cannot recover. We did have a backup system but it went bad for a while and we did not have replacement on time until this
