Hi Everyone,
I am encountering the following issue on a single instance hyper-converged 4.2 setup.
The following fio test was done:
fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=4G --readwrite=randwrite
The results are very poor doing the test inside of a vm with a prealocated disk on the ssd store: ~2k IOPS
Same test done on the oVirt node directly on the mounted ssd_lvm: ~30k IOPS
Same test done, this time on the gluster mount path: ~20K IOPS
What could be the issue that the vms have this slow hdd performance ( 2k on ssd !! )?
Thank you very much !
