MIRRORING LVOLS

Just a quick mirroring question.
When mirroring your lvols is it necessary that they be mirrored in the exact order in which they appear in ,for example, an lvdisplay?
Thanks,
Andy
It is, after all, a matter of survival!!

Re: MIRRORING LVOLS

for vg00 I would recommend it. For others, it's upto you. There may or maynot be performance issues (it all depends on the disks/interface/etc).

Re: MIRRORING LVOLS

On vg00, the first 3 lvols (/stand, swap and /) must be on the same physical disk and contiguous (no interleave). If this is not followed, the mirror will not boot successfully. The rest of the lvols can be interleaved like a deck of cards anywhere you want...but I don't recommend it as it will be a nightmare to manage. It's best to match up mirrors with identical disks on a separate controller.
