RMAN backup fails with I/O error

Oct 4, 2020 3:34AM

Hi All,

Using Oracle 11.2.0.1 SE on OEL 5.5

RMAN backup fails when backed up to NAS but on local disk no issues.

I have run export backups on NAS, no issues. Only RMAN fails.

>>

ORA-19510: failed to set size of 12522973 blocks for file "/u03/nas/dbbkp/ep.20200929.27741_1_1052373049.FULL" (block size=512)

ORA-27045: unable to close the file

Linux-x86_64 Error: 5: Input/output error

Additional information: 4

I have tried setting , but still fails;

allocate channel ch1 type DISK format '/u03/nas/dbbkp/full_%d.%T.%s_%p_%t' MAXPIECESIZE = 2G ;

Please advise.

Thanks
