XFS 错误

诡异：

磁盘SN号居然一样：

# sdparm --quiet -p sn /dev/sda
Unit serial number VPD page:
       WD-WMAZA1508075
# sdparm --quiet -p sn /dev/sdc
Unit serial number VPD page:
       WD-WMAZA1508075

 

# mount /dev/sda1 /data/data027
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

处理办法：

[root@atyu30 ~]# blkid /dev/sdc1
/dev/sdc1: UUID="208a7154-baa3-4159-a6ad-ae16c0938171" TYPE="xfs"
[root@atyu30 ~]# blkid /dev/sda1
/dev/sda1: UUID="208a7154-baa3-4159-a6ad-ae16c0938171" TYPE="xfs"

2个磁盘的UUID居然也一样

修改磁盘UUID

uuidgen 会返回一个合法的 uuid，结合 xfs_admin -U 可以新生成一个 uuid 并写入 xfs 分区中：
比如新建或改变 sdc1 的 uuid （需要 root 权限）

[root@atyu30 ~]# uuidgen
8c922c24-7110-4ba8-9af7-d275ded029b9

[root@atyu30 ~]# xfs_admin -U 8c922c24-7110-4ba8-9af7-d275ded029b9 /dev/sdc1
Clearing log and setting UUID
writing all SBs
new UUID = 8c922c24-7110-4ba8-9af7-d275ded029b9
