[ale] ext3 extended atttributes not supported on ext4?

[Lightner, Jeff]

We were doing a restore from a backup taken off an ext3 filesystem (with defaults in fstab) from an older install to an ext4 on a newer install.   This was mostly successful but on some of the files we saw:

EXT2_IOC_SETFLAGS failed for /database/postgresql/msi/archive/76699438 - Extended Attributes not set. Errno = 95: Operation not supported

On looking into that I find discussion of similar issues when trying to restore from VxFS (Veritas) to ext3 or from UFS (Solaris) to ext3 but nothing regarding ext3 to ext4.

Looking at the man page for this stuff on line it simply says extended attributes are supported by ext2/ext3/ext4.

I’m wondering if my issue is simply that the NetBackup software is calling “EXT2_IOC_SETFLAGS” given that this is ext4.   Is there some compatibility option I can put in my ext4 mount options to make it accept that that call?

Currently I’m having my co-worker create an ext3 filesystem so he can restore to it so we can either then copy from that to the ext4 or simply convert the ext3 to ext4 but I’m thinking it may be simply a compatibility option we need to give it for the restore.
