This change provides mount options for all of the file system types we use. These mount options will ensure that the underlying file systems react with the best possible performance when building a test cloud. The main motivation behind this patch is to help resolve bug 1753790 which is causing sporatic failure when gating on RAX test instances that have a secondary data disks. We were providing no options when mounting a secondary disk which results in using the system defaults which may not be very optimal under general workloads. The options have been added to the bootstrap role and will be consistently applied whenever a given FS is used. > Part of this chagne is to modify the FS type for /var/lib/nova. We were using EXT4 and the recommended FS for VM workloads is XFS. > The mount options have largely been derived from the following posts, https://www.phoronix.com/scan.php?page=article&item=linux414-fs-compare&num=1 https://www.phoronix.com/scan.php?page=article&item=linux-415-fs&num=1 Change-Id: I75e00af687d46551e19178604b60665342cf2cae Closes-Bug: #1753790 Signed-off-by: Kevin Carter <kevin.carter@rackspace.com> |
