OpenStack Object Storage should work on any modern filesystem that supports Extended Attributes (XATTRS). We currently recommend XFS as it demonstrated the best overall performance for the swift use case after considerable testing and benchmarking at Rackspace. It is also the only filesystem that has been thoroughly tested. Consult the OpenStack Configuration Reference for additional recommendations. Install Storage node packages: # apt-get install swift-account swift-container swift-object xfsprogs # yum install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs # zypper install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs For every device on the node you wish to use for storage, set up the XFS volume (/dev/sdb is used as an example). Use a single partition per drive. For example, in a server with 12 disks you may use one or two disks for the operating system which should not be touched in this step. The other 10 or 11 disks should be partitioned with a single partition, then formatted in XFS. # fdisk /dev/sdb # mkfs.xfs /dev/sdb1 # echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab # mkdir -p /srv/node/sdb1 # mount /srv/node/sdb1 # chown -R swift:swift /srv/node # fdisk /dev/sdb # mkfs.xfs /dev/sdb1 # echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab # mkdir -p /srv/node/sdb1 # mount /srv/node/sdb1 # chown -R openstack-swift:openstack-swift /srv/node Create /etc/rsyncd.conf: uid = swift gid = swift log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid address = <STORAGE_LOCAL_NET_IP> [account] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/account.lock [container] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/container.lock [object] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/object.lock uid = openstack-swift gid = openstack-swift log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid address = <STORAGE_LOCAL_NET_IP> [account] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/account.lock [container] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/container.lock [object] max connections = 2 path = /srv/node/ read only = false lock file = /var/lock/object.lock (Optional) If you want to separate rsync and replication traffic to replication network, set STORAGE_REPLICATION_NET_IP instead of STORAGE_LOCAL_NET_IP: address = <STORAGE_REPLICATION_NET_IP> Edit the following line in /etc/default/rsync: RSYNC_ENABLE = true Start rsync daemon: # service rsync start The rsync daemon requires no authentication, so it should be run on a local, private network.
