Hi, I'm trying to resize a 15GB LVM root partition on a fedora20 server with a fedora20 guest and I'm having a problem. Is this supported on fedora20? I recall having a similar problem (maybe even exact same problem) all the way back in fedora16 or fedora17, but hoped/thought it would be fixed by now? # virt-df -h test1-0110...

Simplify how we handle lvm.conf.

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 filte...

Hi everyone, I've read on the gluster & redhat documentation, that it seems recommended to use XFS over LVM before creating & using gluster volumes.

I'm trying to setup a LVM mirror on 2 iSCS targets, but can't. I have added both /dev/sda & /dev/sdb to the LVM-RAID PV, and both have 500GB space. [root at HP-DL360 by-path]# pvscan PV /dev/cciss/c0d0p2 VG LVM lvm2 [136.59 GB / 2.69 GB free] PV /dev/sda VG LVM-RAID lvm2 [500.00 GB / 490...

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. Changes in v2: - dropped patch #5, will be sent separately - move lvmetad statup in own function (patch #2) Thanks, Pino Toscano (4): daemo...

I have a Centos 7 install using EXT4 on LVM. Its running as a VM inside KVM. Issue I have run into is that fstrim does not work due to the LVM. Without fstrim snapshots have gotten huge. Is there a way convert it from LVM to non-LVM without a complete reinstall?

When the daemon starts up it creates a fresh (empty) LVM configuration and starts up lvmetad (which depends on the LVM configuration). However this appears to cause problems: Some types of PV seem to require lvmetad and don't work without it (https://bugzilla.redhat.com/show_bug.cgi?id=1581810). If we don't start lvmetad earlier, the device nod...

This patch reworks how we start up LVM and lvmetad. It fixes the problem we had converting a guest which had a peculiar LVM configuration: https://bugzilla.redhat.com/show_bug.cgi?id=1581810#c14 However please note I have NOT yet tested it fully. Rich.

After some extra reading about LVM snapshots & Gluster, I think I can conclude it may be a bad idea to use it on big storage bricks. I understood that the LVM maximum metadata, used to store the snapshots data, is about 16GB. So if I have a brick with a volume arount 10TB (for example), daily snapshots, files changing ~100G...

Hello all, I am having an issue with guestmount in respect to live instances and I was hoping someone might have an idea where I've gone wrong. The following output is from my shell session, if there's any more information needed please let me know and I'll happily provide it. [root at longitude ~]# virt-filesystems -d F16-rawhide/dev/sda2 /dev/sda3 [root at longitude ~]#

Thanks Rafi, that's understood now :) I'm considering to deploy gluster on a 4 x 40 TB? bricks, do you think it would better to make 1 LVM partition for each Volume I need or to make one Big LVM partition and start multiple volumes on it ? We'll store mostly big files (videos) on this environement. Le 11/10/2017 ? 09:34, Mohammed Rafi K C a ?crit?: > > On 10/11/2017 12:20 PM, ML wrote: >> Hi everyone, >> &g...

Currently lvmetad is started in init, and thus using the system (= appliance) configuration of lvm. Later on, in the daemon, a local copy of the lvm configuration is setup, and set it for use using the LVM_SYSTEM_DIR environment variable: this means only the programmes executed by the daemon will use the local...
