Disclaimer, I am not a programmer but have tinkered with shell and perl scripts. Having said that, I think many would appreciate the option of using gmirror with disks larger than 2T.
The reason this is currently impossible is due to GPT and gmirror both trying to store metadata in the last disk sector. MBR does not allow for partitioning of disk greater 2T. Workaround to gmirror partitions rather than whole disk is less than ideal. Lines 254-293 of geom_mirror.c « mirror « geom « lib - src - FreeBSD source tree <https://cgit.freebsd.org/src/tree/lib/geom/mirror/geom_mirror.c?h=releng/13.0> relate to clearing and storing metadata on last sector of disk. What would be the ramifications of altering gmirror to store metadata on the 2nd to last sector? Am I looking at the correct region to alter this code? -Abner _______________________________________________ freebsd-geom@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-geom To unsubscribe, send any mail to "freebsd-geom-unsubscr...@freebsd.org"
