Hello, Poul-Henning. You wrote 8 октября 2011 г., 12:18:54:
gmirror and this procedure has several problems: 1. It steals the last sector on the disk. If that sector contained data you lost them, with no notice. Most often it will not, particularly on a freshly installed system, but it is still a bad thing.
2. The paritioning is not fixed up to record the stealing of this sector. I wouldn't be surprised if this could cause confusion down the road.
Yes, see discussion about GPT and MBR problems in thread, which is named (and should be re-named already, really) "RFC: Project geom-events"
This is the kind of usage that makes me sad I ever added that option.
Storing metadata of GEOM in last (or first) sector plays bad with MBR and, especially, GPT :( And I cannot see good solution for this.
It seems, that GPT will be incompatible with any pure-software mirror or mirror-like RAID.
