Hi, this series improves the way LVM is used in the appliance: in particular, now lvmetad can eventually run at all, and with the correct configuration. Also improve the listing strategies. Thanks, Pino Toscano (5): daemon: lvm-filter: set also global_filter daemon: lvm-filter: start lvmetad better daemon: lvm: improve filter for LVs with activationskip flag set daemon: lvm: list

Simplify how we handle lvm.conf.

I've been reading up on recommended partitioning scheme and looking at Centos 5 beta's default scheme, it struck me that with LVM, it doesn't matter any more as long as we leave aside enough room for /boot, does it? Or am I still missing something here? Thanks! -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, Today I replaced grub(1) with syslinux on my laptop, after rebooting to syslinux and selecting kernel I got massive freeze along with colorful output to screen - http://i.imgur.com/lFjFc.jpg I think I tried everything, even doing esc and writing after boot: /bzImage-3.1.0, after enter I had the same freeze with the same screen artefacts. How I installed extlinux: mkdir /boot/extlinux

Hi list! I have a 3TB usb drive with an NTFS filesystem on it, that I can't mount.: [bent at bnlaptop ~]$ sudo /sbin/mount.ntfs-3g /dev/sdb1 /mnt Failed to read vcn 0xf28: Input/output error Failed to mount '/dev/sdb1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then

I've been running into a reproducible problem when using default LVM volume group names to present block devices for virtual machines in KVM, and I'm wondering why it is happening. On dom0 I make a default VolGroup00 for the operating system. I make a second VolGroup01 for logical volumes that will be block devices for virtual systems. In VolGroup01, I make two lv's for one system:

I am planning to increase the disk space on my desktop system. It is running CentOS 5.9 w/XEN. I have two 160Gig 2.5" laptop (2.5") SATA drives in two slots of a 4-slot hot swap bay configured like this: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End

Hi, I was wondering, why/when it is useful or when should I avoid to use LVM. I think the big advantage of LVMing is if you modify (rezising, ...) disk and filesystem layouts "a lot". Are there any real pros or cons for following situations regarding e.g. management and speed? e.g.: I do have a server system raid for which the disk layout will not change; e.g. /var /usr /home will

Hello, I miss the system-config-lvm tool for CentOS 7 can I found this on a other place? -- mit freundlichen Gr??en / best Regards, G?nther J. Niederwimmer

Hello, as usual, I'm few years behind trends so I have learned about LVM thin volumes recently and I especially like that your volumes can be "sparse" - that you can have 1TB thin volume on 250GB VG/thin pool. Is it somehow possible to use that with libvirt? I have found this post from 2014: https://www.redhat.com/archives/libvirt-users/2014-August/msg00010.html which says

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

Hi, I didn't find system-config-lvm package on centos 7 official repo's, why? :) Greetings -- -- Sergio Belkin http://www.sergiobelkin.com LPIC-2 Certified - http://www.lpi.org

Hi. I have some narrow questions and a larger one. If I make an existinig LVM VG a storage pool, can I use some of the LV's for libvirt and some for the host? Or does the VG needed to be completely dedicated to virtualization? Assuming mixed use is possible, is it possible to do an LVM snapshot of an LV in use for a VM? The snapshot would have to be initiated and used on the host, I

I have lvm based (thin pool) storage on local disks. I need to move vps from one vg on one disk to another. Does it possible to migrate to localhost with blockcopy migration to another vg? I'm understand that i can move lv from one vg to another, but i don't need that. -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

Dear CentOS-Community, we have a server with four hard drives that are configured as raid10 (/dev/sda). Now, /home and /root are almost full. Therefore, we decided to buy four additional hard drives that should configured also as raid 10 (/dev/sdb). I want to use LVM to extend disk space for root and home. My (successful) test procedure in a virtual environment looks like this: 1. devide

Hi... I have had a problem when I am going to detach one specific LVM partitions of Xen, so I have been trying xm destroy <domain>, lvchange -an <lvm_partition>, lvremove -f.... So I haven''t had sucess. I restarted the server with init 1 yet and nothing... I have seem two specific process started xenwatch and xenbus, but I am not sure if this processes have some action over

I have been reading about software raid. I configured my first software raid system about a month ago. I have 4 500 Gig drives configured in RAID 5 configuration with a total of 1.5TB. Currently I configured the complete individual drivers as software raid, then created a /dev/md0 with the drives I then created a /file_storage partition on /dev/md0. I created my /boot / and swap partitions on

I've upgraded my x86_64 4.2 box to the latest kernel 2.6.9.34 and tried an lvm snapshot. It worked fine and I was able to mount the snapshot etc. Now I cannot seem to remove the snapshot. If I try a 'lvremove' it asks if I want to remove the 'active' snapshot, if I say yes it just hangs and the box goes to 99% wait io, however the disk lights do not come on during this. The
