ORA-19510: failed to set size with ORA-27059: could not reduce file size

Question

Hi,
I have RMAN backup implemented and getting below error.
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on c1 channel at 01/12/2014 04:28:37
ORA-19510: failed to set size of 12839996 blocks for file "/home/oracle/DBBACKUP/Oracle10g1/Full_Backup/DB_Backup_201401128366598241" (blocksize=16384)
ORA-27059: could not reduce file size
Linux Error: 28: no space left on device
Additional information: 2
I have checked with following scenarios:
1. taking backup by setting the MAXSETSIZE parameter value greater than the maximum size of tablespace.
2. taking compressed incremental backup with maxsetsize as unlimited.
3. taking compressed incremental backup with maxpiecesize value as 20G/40G/80G/120G and maxsetsize as unlimited.
Following is the RMAN backup script:
RMAN> run
2>  {
3>  allocate channel c1 device type disk maxpiecesize 120G
4>  format '/home/oracle/DBBACKUP/Oracle10g1/Full_Backup/DB_Backup_%Y%M%D%t%p';
5>  backup incremental level 0 as compressed backupset database plus archivelog delete input;
6>  crosscheck backup of database;
7>  crosscheck backup of controlfile;
8>  crosscheck archivelog all;
9>  delete noprompt expired backup of database;
10>  delete noprompt expired backup of controlfile;
11>  delete noprompt obsolete recovery window of 15 days;
12>  release channel c1;
13>  }
14> exit;
Oracle database version is 10.2.0.1.
The database is on Linux system and we are taking the RMAN backup on mounted Windows NTFS disk.
The remaining space on NTFS system 1.7TB and the total database size 850GB. Used size by database is 500GB.

Hi,
First get the backup piece size its trying to allocate for file "/home/oracle/DBBACKUP/Oracle10g1/Full_Backup/DB_Backup_201401128366598241"
= 12839996*16384
= 210370494464/1024/1024/1024
=195.9GB
Its trying to allocate ~196GB for the file.
1. Make sure the RMAN backup piece won’t exceed the O/S permitted filesize limit.
2. But we can restrict the RMAN backup piece using the MAXPIECESIZE option.
You restricted it to 120GB but actual requirement to allocate backup piece file is ~196GB.
I think you need to change the MAXPIECESIZE and give it a try.
Please update if it succeeded or failed.
Thanks & Regards,
Gayu
