grahamr Posted July 11, 2013 Share Posted July 11, 2013 So - I started a preclear on a drive while it was in an external usb enclosure - needless to say it has been SLOW (48hours for 2tb) its on the last step, the post read- rather than wait the additional 24+ hours to finish, can i stop the process, pop the drive out of the enclosure and resume once on the sata bus? Also, the drive will be a new parity drive - so would it need to finish the post-read step for that? Would assigning it take the array offline for the clear if i dont let the preclear finish? the reason i ask is that the remaining disks are at about 95% and getting this 2tb running will let me get a bit more space and keep using the array i hate rushing things, but knowing its cleared give me confidence in the drive (that and the fact i used it as an external for ~6 months with no issues) Quote Link to comment
itimpi Posted July 11, 2013 Share Posted July 11, 2013 If you run pre_clear script without any parameters it will give you options for running particular phases. Sounds as if you want to run just the pst-read steps? Quote Link to comment
garycase Posted July 11, 2013 Share Posted July 11, 2013 You can't "resume" the pre-clear, but you can, as noted, selectively run parts of it. However ... since you've already used the drive for 6 months, if pre-clear hasn't shown any issues at this point, it's reasonable to assume the drive's okay. You may just want to just install it. And no, there won't be a clearing phase for a parity drive -- it will simply rebuild parity onto the new drive. DO, however, run a parity check on the drive to ensure all is okay BEFORE you remove the old drive !! Hopefully you've already done that while the 2TB drive was pre-clearing. Quote Link to comment
grahamr Posted July 11, 2013 Author Share Posted July 11, 2013 Yep, parity check is all good, no errors on anything at this point. I'll stop this when i get home from the office and then begin the slow process for the rebuild Thanks guys! Quote Link to comment
