請問如何mount 其他cluster 的file system呢

我記得disk 被其他cluster 拿去用過之後

就沒有辦法再mount 到本機(裡面的資料不能刪除)

請問要修改什麼東西才能再mount 起來呢?

Hi,



1) Shutdown all of cluster members.

2) Boot one cluster node to single user mode from the ER (Emergency Repair)system disk that is an original OS before running clu_create.

3) Running these commands as below:

# mount -u /

# mount /usr

# /usr/sbin/cleanPR -show

# /usr/sbin/cleanPR -clean

# /usr/sbin/cleanPR -show

# shutdown -h

4) Remove these disks to the other alpha system. I think all of disks should be mounted.

5) Reboot all of cluster members from the cluster system disk.



Best regards,

Richard.

Hi,



The other solution is run "scu" for clear PR only on Tru64 UNIX V5.1X.



Here is how you get around that:

# scu -f /dev/dsk/dskxx

scu> show keys (this will show you the keys that have the unit reserved)

scu> pres clear key 0 (this will clear the persistent reservation)



_____________________Caution _____________________

Do not run the cleanPR script on a system that is in a cluster.

(/usr/sbin/cleanPR clean command. The cleanPR script finds and clears

all persistent reservations from the attached HSZ80 and HSG80 devices.)



To get rid of the persistent reservations you must either run a

script like cleanPR or use scu (preserve clear) to release each unit. keep

in mind that if there is a cluster that has access to this unit, the

cluster will issue a new PR as soon as it can.
