Created attachment 1189808 [details] verbose lvcreate attempt
This is another one caught by my vg_validate() enhancements. Did we ever support more than 8 DataLVs in any particular RaidLV?
We'll update the package and also 'man lvcreate' to specify the maximum supported limits for each raid type. We'll check the following, but we think the limits are: raid1: -m9 raid10 -i32 (with -m1 limitation) raid0[_meta]: -i 64 raid4/5: -i63 raid6: -i62
Upstream patch: https://git.fedorahosted.org/cgit/lvm2.git/commit/ https://www.redhat.com/archives/lvm-devel/2016-August/msg00064.html
It appears that all the limits are properly checked with the exception of raid10 (filed bug 1370658). This can be marked verified once that is fixed. lvm2-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 lvm2-libs-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 lvm2-cluster-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 ## RAID0 [root@host-117 ~]# lvcreate -i 65 --type raid0 -L 100M -n raid0 test Using default stripesize 64.00 KiB.

Marking this verified with the caveat that bug 1370658 still exists for the raid10 stripe limit.
