I've been running Mint for about a year, and Felicia since it came out. I dual-boot with Windows. I have a partition of about 21 GB for Mint, then a Data partition of about 80 GB that I mount in /home. I also have an external HDD where I keep MP3s and photos. I've already cleared out residual config files from Synaptic and have done an autoclean from terminal.
Recently, on looking at GParted, I noticed that my main partition is almost full--almost 20 GB is used, with "only" about 1.88 GB left. I'm at a loss to understand how my install could have ballooned from something that could be compressed onto a CD to nearly 20 GB. I've installed some programs in the main partition, sure, but nothing that could account for this.
I occasionally get the kernel panic and high CPU usage problems (huge activity by dd and klogd, according to top) outlined in other threads on this forum. (It seems this problem may have something to do with my 4965AGN wireless and the 2.27.7-7 kernel. I'm not sure how or whether to upgrade to 2.27.7-11.) Anyway, I'm wondering if somehow some humungous log files are getting written that eat up my space. Could this be the case, and if so, are those files (if I can find them) safe to delete?
I haven't done an exhaustive sweep yet, but so far, the biggest culprit seems to be /var, which totals 6.8 GB, and specifically /var/log, which totals 6.2 GB all by itself. Within /var/log, I see things like kern.log.0. messages.0, and syslog.0, each of which is 2 GB. Can I kill these without fouling up my system?
Even if I delete all these, my system still would be at around 12 to 13 GB. Is that normal?
