As of mid-day Saturday, Oct. 26, here is what
'/' filesystem space use looks like on this work station: =============== bash.2[/]: df -hP Filesystem Size Used Avail Use% Mounted on tmpfs 7.8G 1.7M 7.8G 1% /run /dev/sda6 50G 24G 23G 52% / /dev/sda7 904G 7.6G 851G 1% /home /dev/sda3 477M 237M 211M 53% /boot [6 others, each using < 1M] ----- bash.3[/]: du -hx -d1 / 6.1G /var 17G /usr 51M /etc 1.4G /root 238M /opt [7 others, each using < 1M] 24G / bash.4[/]: ----- bash.7[/]: du -hx -d1 /var 3.7G /var/cache 847M /var/spool 565M /var/lib 1.1G /var/log [16 others, each using < 1M] 6.1G /var bash.8[/]: ----- bash.8[/]: du -hx -d1 /var/cache 8.0K /var/cache/abrt-di (left in to show results) 144M /var/cache/PackageKit 44M /var/cache/cups 2.9G /var/cache/system-upgrade 6.7M /var/cache/man 501M /var/cache/dnf 60M /var/cache/akmods 2.2M /var/cache/app-info [15 others, each using < 1M] 3.7G /var/cache bash.9[/]: ----- bash.9[/]: du -hx -d1 /var/log 1.8M /var/log/anaconda 2.8M /var/log/ConsoleKit 873M /var/log/journal 1.2M /var/log/gdm 20M /var/log/rkhunter 40M /var/log/audit 9.7M /var/log/upgrade.journal 2.3M /var/log/boot-sav [17 others, each using < 1M] 1.1G /var/log bash.10[/]: ----- Question 1: /var/cache/system-upgrade/updates/packages/ takes up 1.6G and appears to be full of rpm's (1083 of them), each dated 2015 (various months). I do not know the fine details of dnf and rpm. Can I safely delete them, or might that break future patching and upgrading, and other dnf/rmp commands? Question 2: /var/log/ has 193 files that are not sub-directories, and are not stored in sub-directories. 134 are from prior years. Curious: all 134 are from 2016 or earlier; this directory has no files from 2017 or 2018. The files called "messages-[date]" are huge: each over 10M. Can I delete files older than this year safely, or are they needed for something? Question 3: /var/log/rkhunter/ has 184 files, most are from prior years. Am I correct in assuming that I can delete the files from prior years? Question 4: Is there already available some automated deletion of /var/log/ logs (and its sub-directories other than "journal")? Question 5: Are there any other parts of the '/' filesystem that I should clean out and are worth the trouble? thanks, Bill. |
