Description Sahina Bose 2017-07-19 07:13:21 EDT
Description of problem:

I created a VM using disks stored in gluster volume, and ran the sysbench test on it. This caused I/O errors and the disk to be mounted as read-only disk.

# sysbench prepare --test=oltp --mysql-table-engine=innodb --mysql-password=pwd --oltp-table-size=500000000 --oltp-dist-type=gaussian

- Errors in dmesg
[ 2838.983763] blk_update_request: I/O error, dev vdb, sector 0
[ 2842.932506] blk_update_request: I/O error, dev vdb, sector 524722736

How reproducible:

Steps to Reproduce:
1. Create an image on gluster volume mount point using qemu-img create qemu-img create -f qcow2  -o preallocation=off /mnt/glusterlocal1/vm1boot.img 500G
2. Start the VM with additional device as image created in Step 1
3. Install MariaDB and sysbench. Configure database to be on filesystem using device in Step 1
4. Run sysbench prepare

Actual results:
Fails to create data.
