Hello Neil, I want to ask for best solution for replacing device in RAID 6 array. I want to replace device (actually RAID 0 array of two drives), which is working OK but there is known problem with firmware of one drive of that RAID 0 and no solution for it. (It can cause lock up of the drive, which happened to me.) I want to minimize risk of problems on any device / devices during adding new drive, so I am considering other solutions than remove old and add new. - We discussed couple of years ago hot replacing the drive. I see it is now supported in mdadm. Is it rock stable and can be used on production data? I have kernel and mdadm from debian testing, 3.14-2 and 3.3-2. Were there some important fixes from these versions? I have this server on UPS but not on aggregator so there is real danger of power outage and need to shutdown the array during operation. - I can take the array offline. Is it good solution to simply copy the old device to new device? - Or do you suggest as safest solution to remove old device and add new one? Thanks.
