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

2017-11-29 Thread Dmitri Chebotarov
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

unt of data to a single disk. But with LVM striped volumes 'iowait' at around ~20% and I can get to ~750MB/s in the same environment (same config with single disk is ~160MB/s). Also, healing a single large disk on gluster takes ages (I'm using erasure coded volumes) . Thank you, -- Dmitri Chebota

[ovirt-users] Maximum storage per VM?
