hello,

i have a raid 10 with 16 disks with 8tb disks (apx. 58tb) and would like to shrink this raid to a 8 disks - act. used space is apx. 4tb.

my main question is if i must fail devices or can i just use the resize + grow option?
can i specify which disks are the remaining ones?

Personalities : [raid10] [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
md0 : active raid10 sdc[16] sdj[9] sdg[6] sdp[15] sdi[8] sdn[13] sde[4] sdk[10] sdm[12] sdl[11] sdh[7] sdd[3] sdo[14] sdb[1] sdf[5] sda[0]
62511161344 blocks super 1.2 512K chunks 2 far-copies [16/16] [UUUUUUUUUUUUUUUU]
bitmap: 3/466 pages [12KB], 65536KB chunk

it would be cool if do not need to backup/restore all the data and build the raid from scratch.

any help highly apriciated.
thanks
holli
