I guess they are still working on the fix. 06/04/11 If a zfs filesystem is quiesced, either as the result of a DFSMS backup operation or explicitly via a zfsadm quiesce command, the state of the filesystem as displayed by the USS 'df' or D OMVS,F commands will NOT show as QUIESCED. This is a known design issue which is between the LFS (USS) and the PFS (zFS) , and the development teams are currently investigating this. However at this time this is working as designed. Users must be aware that to accurately determine the current status of a zFS filesystem, they must use the provided zfs administration commands: zfsadm lsaggr zfsadm aggrinfo status of the zFS filesystems and will show the status of the filesystem as QUIESCED, if in fact the filesystem is currently in a QUIESCED state. This has become a point of contention recently as backups being taken using the DFSMS DUMP/RESTORE utility will QUIESCE zfs filesystems implicitly. If users are not aware of this activity, they could see temporary 'hang' situations and/or USS Latch contention as indicated by the presence of a BPXM056E errors message displayed to the operators console. To determine ifthe current state of the ZFS filesystems, user are requiredto use the zfsadm commands to accurately determine if ZFS filesystems are QUIESCED ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
