Large mysql table stuck optimizing table

Question

So I am optimizing a table on a unused server. The table has 40+ million records with a size of about 10GB. The optimize has been running for about 5 days. The .TMD file is 9.115 GB the .MYD file is 9.136 GB. The .TMD file has a last modified date of 5 days ago which is about when i started the process. Also i got a warning from cpanel saying that the /tmp directory(4GB) is 100% full. I started this not thinking about the space of the /tmp (new server) My question is could this process still be running and using space else where or is it frozen because of the lack of space?

I don't want to interrupt it and crash the table if i don't have to. I have not seen the size of any files change within the past couple hours. Should i just stop it, repair the table, and add more space to the /tmp dir then restart the optimization?

Any info and suggestions would help. Thanks

I would definetly stop it and restart once you have more space. If it has been running 5 DAYS with no sign of change in the last few hours, then it is definetly frozen.

And if your .tmd and .myd are 9+ gigs, then your /tmp directory should be at least a little larger, since it is possible that the files are all stored in the RAM and at the end are pushed out, you could have ran out of space a long time ago and are just running around in circles ... you know, a endless loop. (but thats just coming from a systems hardware engineer's perspective)
