On RAID prompt, we can type disk list something like this: /dev/sda1,/dev/sdb1,/dev/sdc1,/dev/sdd1 However, if the list has spaces in the list, it doesn't work: /dev/sda1, /dev/sdb1, /dev/sdc1, /dev/sdd1 Because the script mistakenly recognize the space part of a device path. So we need strip() the input for each item. Fixes #8174 Closes #8190
