Subject: uninit block group/mballoc and fsstress

I am hitting this with the below config

mount -t ext4dev $dev /mnt/tmp -o "extents,mballoc"

and running fsstress on /mnt/tmp/

I re-ran the test without the mballoc mount option, but with lazy_bg
enabled, and saw the same error. Error messages and stack are below.

mke2fs -j -I 256 -O lazy_bg $dev
mount -t ext4dev $dev /mnt/tmp -o "extents"

Note that "-O lazy_bg" has nothing really to do with the uninit_groups
feature. Also, if you don't have the CFS e2fsprogs patches for
uninit_groups then mke2fs creates an invalid filesystem if the journal is
large (this was an unrelated bug we fixed while testing uninit_groups).
Try running e2fsck right after the above mke2fs and you will likely
see errors.

The problem is that lazy_bg allocates the journal blocks incorrectly, IIRC.

e2fsprogs found at

ftp://ftp.clusterfs.com/pub/lustre/other/e2fsprogs

sets unint with -O lazy_bg. Is there any other option that i can use to set
the uninit block group feature ?

Yes, "-O uninit_groups". Note that while "-O lazy_bg" does set the UNINIT
flags on the groups (this is a COMPAT feature that marks all of the groups
full in the group descriptors), it does NOT handle the inode high watermark
or in-kernel initialization of the bitmaps.
