Symptom
The Database recovery after HANA 2.0 Upgrade turned erroneous and it failed with disk full error on the Quality Database-ABC.
After adding 1.5 TB on each data volume of ABC database, restarted the recovery once again and it worked fine.
The data volumes size on ABC(Test) as same as the production database CDF(Prod) volumes as example:
Disk Volumes on ABC
PATH | FILESYSTEM | AVAIL_GB | USED_SIZE_GB | UNUSED_SIZE_GB | FRAGMENTATION_PCT | LOCAL MOUNT POINT |
hbabcd03-nfsp2:/ABC_data_mnt00002 | NFS | 4.0T | 2.7T | 1.4T | 66% | /hana/data/ABC/mnt00002 |
hbabcd03-nfsp4:/ABC_data_mnt00004 | NFS | 4.0T | 2.8T | 1.3T | 68% | /hana/data/ABC/mnt00004 |
hbabcd03-nfsp3:/ABC_data_mnt00003 | NFS | 4.0T | 2.9T | 1.2T | 72% | /hana/data/ABC/mnt00003 |
hbabcd03-nfsp1:/ABC_data_mnt00001 | NFS | 2.5T | 1015G | 1.6T | 40% | /hana/data/ABC/mnt00001 |
Disk Volumes on CDF:
PATH | FILESYSTEM | AVAIL_GB | USED_SIZE_GB | UNUSED_SIZE_GB | FRAGMENTATION_PCT | LOCAL MOUNT POINT |
hbefgh12-nfsp4:/CDF_data_mnt00004 | NFS | 2.5T | 1.7T | 821G | 68% | /hana/data/CDF/mnt00004 |
hbefgh12-nfsp2:/CDF_data_mnt00002 | NFS | 2.5T | 1.6T | 956G | 63% | /hana/data/CDF/mnt00002 |
hbefgh12-nfsp3:/CDF_data_mnt00003 | NFS | 2.5T | 1.8T | 769G | 70% | /hana/data/CDF/mnt00003 |
hbefgh12-nfsp1:/CDF_data_mnt00001 | NFS | 2.5T | 1.4T | 1.2T | 53% | /hana/data/CDF/mnt00001 |
This example shows, that the disk is heavily de-fragmented during Recovery phase.
