Re: How to detect when LVM RAID1 is in sync for write mostly?

Hello!

     I have RAID1 configured on my home system. I replaced 2 disks there 
and usually use lvs to see if it's in sync:

[root@srv ~]# lvs

       LV       VG          Attr          LSize  Pool Origin Data%  
Meta%  Move Log Cpy%Sync Convert
   storage  kurisu rwi-aor--- <3,64t                                     
             100,00

AFAIU, writes are syncronious. So if the number is 100, you're good.

Also, there's an integrity check command.
