Question about metas
Hi
I have a question about metas.
When I create a meta I use consecutive devices, I mean, someting like this
06B3
06B4
06B5
06B6
06B7
06B8
06B9
form meta from dev 06B3 config=striped, stripe_size=1920;
add dev 06B4:06B9 to meta 06B3;
The problem here is, I have diferentes groups devices, I mean, I have 5 dev consecutives, another 5 dev consecutives something like this
0184
0185
0186
0187
0188
022A
022B
022C
022D
022E
is it posible to make a meta by using diffentes consecutives devices, I want to use these 10 devices in a metalun.
Regards

Long answer: the only "issue" with non-consecutive symdevs is that it's hard to predict if the devices belong to different drives in the backend .. However even using consecutive symdevs doesn't avoid the problem ('coz you may have a few consecutive symdevs build out of a small number of drives, a small capacity upgrade).

Form meta from dev , config =Stripped, stripe_size=1920, count=10;
the above command will let DMX select 10 devices best suited for the meta
or you can use
Form meta from dev , config=Stripped, stripe_size=1920;
add dev to meta ;
add dev to meta ;
