Error description

  • mksysb (or backbyname) may hang while trying to backup
    a soft link to another filesystem that doesn't responds.
    If /usr/link is a link to /otherfs and /otherfs is a
    filesystem that doesn't responds (NFS, autofs, gpfs, gsa,
    etc...) the mksysb (or backbyname will hang).
    This is due to the backbyname using standard stat
    functions
    to backup extended attributes instead of using ones that
    don't follow the link.
    

Local fix

  • Fix the filesystem mount hang.
    Or exclude the file from the backup or mksysb (link will
    need to be rebuilt manually after restore)
    

Problem summary

  • mksysb (or backbyname) may hang while trying to backup
    a soft link to another filesystem that doesn't responds.
    

Problem conclusion

  • Enable appropriate control flags for usage by backbyname.
