Restoring backup piece containing 580G of dbf on 800G diskgroup fails with ORA-15041 space exhausted
Hello,
In 19c I tried to restore a database hosted on a server, on another machine, from following backup piece:
machine $ ls -l /path/to/DB_BACKUPS/<RMAN bkp piece>
-rw-r-----. 1 oraaaaaa asmadmin 408399609856 Jul 1 18:28 /path/to/DB_BACKUPS/<RMAN bkp piece>
so this backup piece is 380G in size, and contains around 30 datafiles amounting to 580G on diskgroup +DATA.
After a while it finally failed with
ORA-19870: error while restoring backup piece /path/to/DB_BACKUPS/<RMAN bkp piece>
ORA-19504: failed to create file "+DATA"
ORA-17502: ksfdcre:4 Failed to create file +DATA
ORA-15041: diskgroup "DATA" space exhausted
Column Total_MB of diskgroup +DATA in ASMCMD shows 1638384 (= 800G of space as we are in normal redundancy).
