Error Message

GRO Mount Error message:

Error E0A20065: Running OS does not support file system containing in the volume of the recovery point.

Error E0A20066: Mounting of recovery point failed.

SRD Restore Issue:

The machine goes into emergency mode after restoring from SRD restore and rebooting.

New file attribute feature “64bit” is added in the SLES12 SP4 operating system. (See Figure 1)

Figure 1

Enabling the 64bit feature increases the data structure size so that full 32-bit checksums can be stored for many data structures.

This feature is related to supporting the larger filesystem of 16TiB . With this feature ON, Veritas System recovery Linux Edition smart sector copy does not work, and the image size is larger than expected, and failure of GRO-mount and OS-boot after SRD restore are observed.

Workaround:

Please disable the file attribute feature “64bit” with command resize2fs -s.
The steps are as follows.

1.    Unmount the partition (example: umount  /dev/sda2). For root partition, unmount needs to done in rescue mode.

2.    Execute the command e2fsck -f /dev/sda2

3.    Execute the command resize2fs -s /dev/sda2

4.    Mount the partition mount /dev/sda2

5.    Reboot the Linux server.
