Hello friends,
Few days back we detached our aws instance ver60 volumes as the HDB(thru studio as well as hdbsql) was not working and we had tried all possible solutions we could find but finally we had to create a new ver80 aws instance and restore our schemas and views to resume our HANA work.
But I had not taken a copy/backup of some long linux(HANA related) scripts(which I coded) and are residing in a specific directory of hana linux server.
To retrieve them I have reattached the volumes to the old instance(ver60) but except the root /dev/sda1 volume others are not getting MOUNTed
When i run the mount command in either form i get following errors:
imdbhdb:~ # mount -t ext3 /dev/sdf /usr/sap
mount: wrong fs type, bad option, bad superblock on /dev/sdf,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
imdbhdb:~ # mount /dev/sdf /usr/sap
mount: unknown filesystem type 'linux_raid_member'
I followed the procedure given in the link Installing SAP HANA SPS 7 on AWS (except the formatting part as it will delete my data).
Initially the " /etc/fsad " file had the following script inside
/dev/sda1 / ext3 acl,user_xattr 1 1
/dev/sdb /mnt ext3 acl,user_xattr 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/md0 /sap ext3 defaults,noatime 0 0
but to mount my volumes I created the folders as specified in the above link and changed the file " /etc/fsad " as follows:
/dev/sda1 / ext3 acl,user_xattr 1 1
/dev/sdf /usr/sap ext3 defaults 0 0
/dev/sdg /hana/data ext3 defaults 0 0
/dev/sdh /hana/log ext3 defaults 0 0
/dev/sdi /hana/shared ext3 defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/md0 /sap ext3 defaults,noatime 0 0
but when i restart my instance to enable the mount I get a file in " /sap/usr " path named " dsod_init.log " with following content:
su: warning: cannot change directory to /usr/sap/HDB/home: No such file or directory
-sh: /usr/sap/hana_sso_config_part1.sh: No such file or directory

Kindly help me with this issue as those linux scipts took a lot of my time and I am desperate to recover them.
Thanx a lot.
