| Growfs on 6.X will destroy your UFS2, and mabye UFS1, filesystem.
| The patch in bin/115174 appeared to fix growfs but I recently had
| a file system related panic on a machine with a growfs expanded
| filesystem.
|
|   reboot after panic: ffs_alloccg: map corrupted
|
| That panic may be unrelated to growfs but that machine is the only
| 6.3 machine I have in production with a grown file system.  The
| 800G fileystem had a few percent used when it paniced.  It was being
| brought into service as a Cyrus IMAP replica.
|
| A working growfs was a requirement for me to move from rock solid
| 4.11.  It would really be nice if the filesystem guru's could take
| a look at the growfs problem.

For now I will skip the growfs.

If the controller migrate the level w/o any data lost will be great - I
will do additional partition afterwards.

I will send update.
