[Gluster-users] trusted.ec.dirty attribute

Hi I've got a problem on a EC volume where heal doesn't seem to work for just few files (heal info shows no progress for few days, Warning on the client mount) I ran getfattr -m . -d -e hex / across all servers in the cluster and 'trusted.ec.dirty' attr is non-zero on all files which don't

Re: [Gluster-users] [ovirt-users] slow performance with export storage on glusterfs

Hello If you use Gluster as FUSE mount it's always slower than you expect it to be. If you want to get better performance out of your oVirt/Gluster storage, try the following: - create a Linux VM in your oVirt environment, assign 4/8/12 virtual disks (Virtual disks are located on your Gluster

Re: [Gluster-users] warning spam in the logs after tiering experiment

Hi Alastair I apologize my email is off topic, but I also have strange issues on a volume and it happened to be volume with hot-tier attached to it in past. Can you do me a favor and test something on the volume where you used to have hot-tier? I'm working with RH on issue where glusterfs fuse

Re: [Gluster-users] dbench

Can you check if you right options enabled for the volume? Check /var/lib/gluster/groups/virt file. Ignore shard options since you already configured it (I think recommended shard size is 512mb)... How is the performance on mounted glusterfs-fuse on the host? On Thu, Oct 12, 2017 at 16:45

Re: [Gluster-users] ZFS with SSD ZIL vs XFS

I've had good results with using SSD as LVM cache for gluster bricks ( http://man7.org/linux/man-pages/man7/lvmcache.7.html). I still use XFS on bricks. On Tue, Oct 10, 2017 at 12:27 PM, Jeff Darcy wrote: > On Tue, Oct 10, 2017, at 11:19 AM, Gandalf Corvotempesta wrote: > >

[Gluster-users] sparse files on EC volume

Hello I'm running some tests to compare performance between Gluster FUSE mount and formated sparse files (located on the same Gluster FUSE mount). The Gluster volume is EC (same for both tests). I'm seeing HUGE difference and trying to figure out why. Here is an example: GlusterFUSE mount: #

[Gluster-users] RECOMMENDED CONFIGURATIONS - DISPERSED VOLUME

Hi I'm looking for an advise to configure a dispersed volume. I have 12 servers and would like to use 10:2 ratio. Yet RH recommends 8:3 or 8:4 in this case: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/chap-Recommended-Configuration_Dispersed.html

Re: [Gluster-users] gluster volume 3.10.4 hangs

Hi With only two nodes it's recommended to set cluster.server-quorum-type=server and cluster.server-quorum-ratio=51% (i.e. more than 50%). On Mon, Jul 31, 2017 at 4:12 AM, Seva Gluschenko wrote: > Hi folks, > > > I'm running a simple gluster setup with a single volume

[Gluster-users] Hot Tier

Hi I'm looking for an advise on hot tier feature - how can I tell if the hot tier is working? I've attached replicated-distributed hot tier to an EC volume. Yet, I don't think it's working, at least I don't see any files directly on the bricks (only folder structure). 'Status' command has all 0s
