Can I run more than one preclear script at the same time on the same tower?

 

I just did this by opening separate telnet sessions and running pre-clear in each one for different drives.  Worked fine.  Just be sure to leave the telnet sessions open and be sure the client computer stays on.

Thx. I have 2 running now

I have 1 running on 3 disc's on my first server now

 

how many should we run on each disc?

You can use Screen to run them without needing to keep Telnet open.

Don't invoke multiple scripts on the same disk at the same time...  but the answer to your question depends on you.  Some people like to run several cycles, some only one. Others only run subsequent cycles if the first turns up sectors being re-allocated or pending re-allocation.  If additional cycles result in additional sectors being re-allocated or marked as pending re-allocation you probably do not want the drive in your array.  If after running several more pre-clear cycles no additional re-allocated sectors result, you are probably ok.

 

 

sorry to Hi-jack....

 

Thanks Guys....the first of the 3 finished and at least this one is good then based off of 1 preclear cause if im reading this right then there aren't any reallocated or pending sectors

If that is the smart report after the preclear script had finished, it looks great.

WOOHOOO....

 

Only 2 drives to go....lol

 

yes...this is from the email I received after it finished

Also look for extra Start_Stop_Count and Power_Cycle_Count. If they change it indicates a power problem.
