今天我重启系统时,发现两个分区不能mount成功。之前并没有做过什么操作,另外,这两个分区是来自san storage的LUN,请各位高手指点一下uuid可能改变的原因!
操作过程如下:
1、重起操作系统,用命令mount -a,提示如下:
ESHMS4:~ # mount -a
mount: special device /dev/disk/by-uuid/d0e514e5-0e12-475c-bdd8-b367c3b86096 does not exist
mount: special device /dev/disk/by-uuid/b0da4411-f24a-47f4-8b67-8f0dd2efaf89 does not exist
2、操作系统中fstab文件信息如下:
ESHMS4:~ # cat /etc/fstab
/dev/disk/by-id/scsi-3600508e000000000a25470d4dc1b2604-part2 / reiserfs acl,user_xattr 1 1
/dev/disk/by-id/scsi-3600508e000000000a25470d4dc1b2604-part1 swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
# Added by /usr/sbin/SAPinit on 2010-07-15 04:43:14 CST (2010-07-14 20:43:14 UTC).
shm /dev/shm tmpfs size=9g 0 0
UUID=d0e514e5-0e12-475c-bdd8-b367c3b86096 /home/hms/data/c auto noatime 0 0
UUID=b0da4411-f24a-47f4-8b67-8f0dd2efaf89 /home/hms/data/d auto noatime 0 0
3、用命令blkid查看磁盘UUID如下:
ESHMS4:~ # blkid
/dev/sda1: TYPE="swap"
/dev/sda2: UUID="4bbfe96a-de1d-4735-837a-cc7c60b3b21f" TYPE="reiserfs"
/dev/sdb: UUID="5a152fe0-9493-4183-9b87-22ab062f5b17" TYPE="xfs" (从这里可以看出,UUID跟原来的不一样了)
/dev/sdc: UUID="83d5ad25-42eb-4bf8-ab8d-8a6a8bd24e28" TYPE="xfs" (从这里可以看出,UUID跟原来的不一样了) |
