It looks like the patch for LU-7497, https://review.whamcloud.com/#/c/25940/. fixed this issue by not turning on the MGS service in the disk image.

I'm not closing this ticket because it looks like more work is necessary. From the commit message of 25940:

It turned out that the MGS svc was wrongly turned on in disk image
'disk2_4-zfs.tar.bz2', which caused the OST mount failure with
EALREADY because the MGS service has already been started by the MDS.

This is just a temporary solution and the final fix would be to clean
the disk image in question.
