Openstack Swift 如何查找 slave node 挂载的 VD 的 IP

1. 在 /etc/swift/container-server.conf 或者 object-server.conf 中的 devices= 一行 可以找到 /srv/node.

    在 /srv/node/ 下可发现设备， 如 sdb. 即 /srv/node/sdb

2. 通过命令 cat /etc/fstab 可以得到如下信息

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=2d666d5f-aedf-4130-b51e-4296661b07d2 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=aa7c8c0e-46ba-44c5-b11e-ab384d6669d1 none            swap    sw              0       0
/dev/disk/by-path/ip-10.666.1.666:3260-iscsi-iqn.2002-03.com.666:storage.666-dg.6661-lun-0 /srv/node/sdb ext4 _netdev 0 0

即可得到 ip。
