We've been working to clean up some space in our
/opt mount. A large culprit of space consumption was log files for some processes we run (to the tune of 2 to 12 GB each).
We've cleaned these up by truncating them. However, this seems to be skewing our output from
/dev/mapper/Sys-opt 76G 72G 0 100% /opt
du -sh * on this directory, the sizes don't add up. When running
lsof | grep log, I see that many of the files we've deleted still show up with
(deleted) appended to the end.
My question is, (a) should I be concerned with this?, and (b) is there a way to get my
df -H back to normal, without restarting the box / these processes? Will restarting the processes even fix it (I see several entries for the same logs, which are from processes I know have been restarted recently)?
