OpenStack Caracal : Configure Swift (Storage Node)2024/05/22

 

Configure OpenStack Object Storage (Swift).

This example is based on the environment like follows.

------------+--------------------------+------------
            |                          |
        eth0|10.0.0.30             eth0|10.0.0.50

Configure Storage Node on this section.
It's OK to set the same settings mostly on all Storage Nodes, but only IP address are different each other.
For storage partition, it needs enough size of free area on disks to create new partitions.

[1] On all Storage Nodes, Install Swift-Account, Swift-Container, Swift-Object and others on all Storage Node like follows.
root@snode01:~#
apt -y install swift swift-account swift-container swift-object xfsprogs
[2] Format free space of disk ([/dev/sdb1] on this example) with XFS and mount on [/srv/node/device] on all Storage Node like follows.
root@snode01:~#
mkfs.xfs /dev/sdb1

meta-data=/dev/sdb1              isize=512    agcount=4, agsize=10485696 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=1
         =                       reflink=1    bigtime=1 inobtcount=1 nrext64=0
data     =                       bsize=4096   blocks=41942784, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=20479, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
Discarding blocks...Done.

root@snode01:~#
mkdir -p /srv/node/device

root@snode01:~#
mount -o noatime,nodiratime /dev/sdb1 /srv/node/device

root@snode01:~#
chown -R swift:swift /srv/node
root@snode01:~#
blkid | grep sdb1

/dev/sdb1: UUID="13738d6d-999a-402a-9abd-2f436e2c5c4b" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="3cfdf937-01"

vi /etc/fstab

/dev/disk/by-uuid/13738d6d-999a-402a-9abd-2f436e2c5c4b /srv/node/device xfs defaults,noatime,nodiratime 0 0
[3] Copy Swift Ring files from the Swift Proxy Node to all Storage Nodes.
root@network:~#
scp /etc/swift/*.gz 10.0.0.71:/etc/swift/

account.ring.gz                    100% 3912     3.8KB/s   00:00
container.ring.gz                  100% 3904     3.8KB/s   00:00
object.ring.gz                     100% 3895     3.8KB/s   00:00
[4] Configure Swift and Rsync on all Storage Nodes.
root@snode01:~#
chown swift:swift /etc/swift/*.gz

root@snode01:~#
vi /etc/swift/swift.conf
# set the value which is set on Proxy Node

[swift-hash]
swift_hash_path_suffix = swift_shared_path
swift_hash_path_prefix = swift_shared_path
