Cluster切换问题

jackyleelq

有主、备两台机器，主机切到备机上时，直接把主机的文件系统mount到备机上了，而备机上的文件系统不动

我现在想：

在切换的时候，先把备机上的部分文件系统umount掉，在mount上主机的文件系统。不知道可否实现？如何修改cluster配置文件？

不知道大家看明白没有，望指教

看一下MCSG的手册，命令就都有了（到HP网站下一下）。

‘切换’行为实际是VGs控制权在主备机间的‘传递’；mount等问题，能在配置文件、脚本里设（看你MC是什么版本了，有差异）

文件系统的切换，用MC/SG的package就能搞定。配置文件中有写VG,LV,FS以及mount_point信息的地方。

ctrl文件里，是这一块吧：

# FILESYSTEMS
# Filesystems are defined as entries specifying the logical volume, the
# mount point, the mount, umount and fsck options and type of the file system.
# Each filesystem will be fsck'd prior to being mounted. The filesystems
# will be mounted in the order specified during package startup and will
# be unmounted in reverse order during package shutdown. Ensure that
# volume groups referenced by the logical volume definitions below are
# included in volume group definitions above.
#
# Specify the filesystems which are used by this package. Uncomment
# LV[0]=""; FS[0]=""; FS_MOUNT_OPT[0]=""; FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""
# FS_TYPE[0]="" and fill in the name of your first logical volume,
# filesystem, mount, umount and fsck options and filesystem type
# for the file system. You must begin with LV[0], FS[0],
# FS_MOUNT_OPT[0], FS_UMOUNT_OPT[0], FS_FSCK_OPT[0], FS_TYPE[0]
# and increment the list in sequence.
#
# Note: The FS_TYPE parameter lets you specify the type of filesystem to be
# mounted. Specifying a particular FS_TYPE will improve package failover time.  
# The FSCK_OPT and FS_UMOUNT_OPT parameters can be used to include the
# -s option with the fsck and umount commands to improve performance for
# environments that use a large number of filesystems. (An example of a
# large environment is given below following the decription of the
# CONCURRENT_MOUNT_AND_UMOUNT_OPERATIONS parameter.)
#
# Example: If a package uses two JFS filesystems, pkg01a and pkg01b,
# which are mounted on LVM logical volumes lvol1 and lvol2 for read and
# write operation, you would enter the following:
#      LV[0]=/dev/vg01/lvol1; FS[0]=/pkg01a; FS_MOUNT_OPT[0]="-o rw";
#      FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""; FS_TYPE[0]="vxfs"
#
#      LV[1]=/dev/vg01/lvol2; FS[1]=/pkg01b; FS_MOUNT_OPT[1]="-o rw"
#      FS_UMOUNT_OPT[1]=""; FS_FSCK_OPT[1]=""; FS_TYPE[1]="vxfs"
#
#LV[0]=""; FS[0]=""; FS_MOUNT_OPT[0]=""; FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""
#FS_TYPE[0]=""

要mount，就这么写
LV[0]="/dev/vg01/lvol1"; FS[0]="/pkg01a"; FS_MOUNT_OPT[0]="-o rw";FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""; FS_TYPE[0]="vxfs"

但，要umount，该怎么写？

自动umount，不用标注什么

难道LZ实现不了？

要不就自己写脚本, 把信息导出到map文件候umount, 需要是再整回来

楼主问的是这个意思吗?
我还真没看懂
