Error description

  • On a 6.1.7.6 lpar with the wpar at the same level, a
    change
    to a FS, such as a mount point and mount=true/false do
    not
    get preserved across a save/remove/restore sequence. The
    wpar is a rootvg wpar.
    
    The /home FS inside the wpar was the target of change:
    ??? umount /home
    ??? chfs -a mount=true -m /pw/home /home
    
    stopwpar followed by startwpar shows the /pw/home
    mounted.
    
    But the following save/restore sequence does not bring up
    the wpar with the /pw/home:
    
    savewpar
    stopwapr
    rmwpar
    cfgmgr
    restwpar
    startwpar
    clogin
         # mount - shows /home, not /pw/home on hd1
             /dev/hd1         /home            jfs2   Nov 12
    11:15 rw,log=INLINE
    
    # grep -p "home" /etc/filesystems
    /home:
            dev             = /dev/hd1
            vfs             = jfs2
            log             = INLINE
            mount           = true
            check           = false
            type            = pwxobbwtest1
            account         = false
    
    /pw/home:
            dev             = /dev/wlv6
            vfs             = jfs2
            log             = INLINE
            mount           = false
            check           = false
            type            = pwxobbwtest1
            quota           = no
            account         = false
    
    Even changing mount=true, for /pw/home will only bring it
    up as an additional mounted FS.
    
    Similarly adding a new FS, say, /var/adm/toibm inside the
    wpar also does not get its FS attrs preserved and shown
    on restwpar.
    

Local fix

  • Since it is an issue of /etc/filesystems inside the wpar
    not honored when restwpar is done, one may temporarily
    use
    a workaround of saving the /etc/filesystems inside the
    wpar
    as a separate file, outside the savewpar. Then after
    restwpar one could restore that one separate file too,
    then
    it should be ok.
    

Problem summary

  • /home file system renamed to /xxx/home not preserved properly
    by restwpar of a rootvg WPAR.
    

Problem conclusion

  • Corrected restwpar to preserve additional information from
    /etc/filesystems
    

Temporary fix
