Re: Cant find sunit and swidth on luks encrypted raid6 device

Hi, Eric

Here is the output you wanted. I also did some debuging with strace but its
kinda big to paste it in here.
I also tried with the size option using a smaller device size which was
working but still using wrong optimized values for the raid6 device.
I guess you found the bug up there so should I add that and recompile
xfsprogs to try again ?

mkfs.xfs -f -dsize=5t /dev/mapper/raid6

meta-data=/dev/mapper/raid6      isize=256    agcount=32, agsize=41943040
blks
         =                       sectsz=512   attr=0
data     =                       bsize=4096   blocks=1342177280, imaxpct=25
         =                       sunit=0      swidth=0 blks, unwritten=1
naming   =version 2              bsize=4096
log      =internal log           bsize=4096   blocks=32768, version=1
         =                       sectsz=512   sunit=0 blks, lazy-count=0
realtime =none                   extsz=4096   blocks=0, rtextents=0


Here is the output of blockdev and proc:

blockdev --getsize64 /dev/mapper/raid6
7000893943808

cat /proc/partitions
