Hello, I added an extra drive to an existing Raid 5 array which consisted of 6 drives, now of course with the additional drive it will make it 7. However, the speed of the reshape is going at 8877K/sec and sometimes goes into 9000K/sec range however it does not go above this. I've changed all the parameters to make it go faster for the reshaping process which includes /proc/sys/dev/raid/speed_limit_min and /proc/sys/dev/raid/speed_limit_max. These were changed to 50000 each. That did not help. I then made another change which was blockdev --setra 16384 /dev/md0. Again nothing changed. However, I do think that my drives are too close to each other causing more heat and possibly causing issues with the reshaping process due to some of the errors I see in the log files. I see some of the drives complaining about being hard reset. I was dumb and stacked them pretty close to each other and before since they were not under heavy use, there were no problems... however now that the drives are under heavy use... I am seeing these errors come up. I'd like to re-arrange the drives so they have more airflow and also help try and prevent the errors from showing. So with that in mind, would it be at all possible to stop the reshaping process, re-arrange the drives, then get the reshaping process back up and running? Or would it be better for me to just wait until the reshaping process is completed? Right now I'm look at another day to complete the process. If all goes well and I think it will... (first time doing this) I would like to add another drive to the array however, I don't want this to be my experience every time I add an additional drive to it. I am a bit new to Linux so if I got some of the terminology wrong please forgive me. Oh, and if there is a way to stop the reshape process safely and have it restart after re-arranging of the drives, please let me know the proper procedure to this being done. Thanks for everyone taking their time reading this and any help anyone can provide. -Jeremy -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
