Database Software

Hi everybody,

I'm trying to restore a level 0, 11g Standard One (on RedHat 6.2), 19GB db on a remote server.

Although there are over 45GB free disk space and both user oracle and group oinstall have create/delete rights on folder backupset, I get the following error when I try to backup (and no folder 2013_04_26 is created):

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 04/26/2013 11:31:58
ORA-19502: write error on file "/home/oracle/rman/ORCL/backupset/2013_04_26/o1_mf_nnnd0_TAG20130426T042617_8qngkl50_.bkp", block number 120320 (block size=8192)
ORA-27072: File I/O error
Additional information: 4
Additional information: 120320
Additional information: 462848

Please note that local backup worked fine.

I also tried to duplicate the db (from the auxiliary server) without success, getting for all target files following errors (here I copied those for only one of them), although all backup files exist in their corresponding folders:

channel ORA_AUX_DISK_1: starting datafile backup set restore
channel ORA_AUX_DISK_1: restoring control file
channel ORA_AUX_DISK_1: reading from backup piece /home/oracle/rman/ORCL/backupset/2013_04_09/o1_mf_ncsn0_TAG20130409T062510_8p7v48nq_.bkp

ORA-27037: unable to obtain file status

failover to previous backup
