I'm attempting to build an array using mdadm. The array has 512-byte (not kibibyte) sized stripes. Because mdadm accepts arguments to chunk in kibibytes, not in bytes, I have been unable to build this array correctly.
mdadm --build -n2 -c512 -lraid0 /dev/md0 /dev/sdb /dev/sdc
Builds the array with chunk size 512 KiB.
mdadm --build -n2 -c.5 -lraid0 /dev/md0 /dev/sdb /dev/sdc
Returns an error.
Any ideas? I would normally just manually rebuild the RAID. But this one is 4TB big. I could rebuild it to an LVM, but I was hoping to avoid this. Any ideas?
