SAP HANA Backup error

[Former Member]

Hi all,

When trying to run a Backup in HANA Studio we get an message/error which reports that the backup is failing.

The shared folder where the backups will be stored has the necessary permissions set.

The error we get is:

Could not start backup of system 'SH1'. ' Cannot open file ""<root>/.log_backup_0_0_0_0.1385931567067" (mode= W, access= rwrwr-, flags= DIRECT|UNALIGNED_SIZE|TRUNCATE|MULTI_WRITERS), factory= (root= "/mnt/backup/log/" (access= rwrwr-, flags= AUTOCREATE_PATH|DISKFULL_ERROR, usage= LOG_BACKUP, fs= UNKNOWN (cifs), config= (AsyncWriteSubmitActive=auto,AsyncWriteSubmitBlocks=new,AsynReadSubmit=off,#SubmitQueues=1,#CompletionQueues=1)))", rc=22: Invalid argument'

Does anyone have an idea of what we can check to resolve this error?

Thanks in advance!

Hi Dries,

Can you check the free size in /mnt/backup/log.

What is the value of parameter log_mode

The log_mode is set to 'normal', the backup folder is mounted to a network share.

The free space on this share is 843G, so I'm not sure why it says DISKFULL_ERROR in the flags.

Hi,

Did you try creating an empty file in that location as the HANA OS user itself?

Try running "touch abc" in the location. If that succeeds try adding some data to the file "abc" using VI editor.

I got a similar problem today but in my case the flag was AUTOCREATE_DIRECTORY.

Thanks,

Jackson
