Out-of-Space during Sync processing z/OS DFSMSdfp Diagnosis SC23-6863-00 |
|
HFS writes a LOGREC record and a console message when it encounters the out-of-space condition during Sync processing. The file system will not function correctly when it is in this state. Some requests will return an error with a return code of ENOSPC (00000085x) and a reason code of 5Bxx0E37x. As soon as possible, the file system should be evaluated and any necessary corrective actions taken. For more information, see message IGW022S in z/OS MVS System Messages, Vol 9 (IGF-IWM). If the file system is unmounted at this point, any updates that were made to the file system since the last successful Sync are lost, and the file system reverts to the state it had after the last sync. HFS writes the following message to the LOGREC and console:
If confighfs is used to successfully extend the
file system, for
example
and
the extent
was large enough to accommodate the pages required to complete the
sync processing, confighfs reinvokes the sync function to complete
its update, not loosing the updates made since the last successful
sync. The HFS Out- of- Space error flag is reset and all file system
functions wilI work properly again. It will no longer be necessary
to unmount and remount the file system to use it further. If
the extend amount is not large enough to provide the space
required to complete the sync process, confighfs will issue the following
response:
Note: This fix ONLY applies for the case when the IGW022S
message indicates an Error Loc: EXTEND value. If it indicates an Error
Loc: ARPN value, it will continue to function as it did prior to this
update.
