After migrating from Ubuntu 18.04 to Ubuntu 20.04, my CPU is burning hot and disk activity is off the charts, while this seemingly un-killable set of processes slams my CPU and harddisk:
tracker-miner-fs
tracker-extract
tracker-store
In the process of trying to understand what is going on, I came across this most curious behavior in a bash session:
user@computer:/tmp$ cd tracker-extract-files.121
bash: cd: tracker-extract-files.121: Permission denied
user@computer:/tmp$ sudo cd tracker-extract-files.121
[sudo] password for user:
sudo: cd: command not found
user@computer:/tmp$ sudo cd tracker-extract-files.121
sudo: cd: command not found
user@computer:/tmp$ ls -al tracker-extract-files.121
ls: cannot open directory 'tracker-extract-files.121': Permission
denied
user@computer:/tmp$ sudo ls -al tracker-extract-files.121
total 8
drwx------ 2 gdm gdm 4096 Jan 22 17:26 .
drwxrwxrwt 19 root root 4096 Jan 23 10:39 ..
user@computer:/tmp$ sudo ls -al tracker-extract-files.121/gdm
ls: cannot access 'tracker-extract-files.121/gdm': No such file or
directory
user@computer:/tmp$ sudo ls -al tracker-extract-files.121/root
ls: cannot access 'tracker-extract-files.121/root': No such file or
directory
I also tried to run the command "renice" for the running processes but the PID keep changing like it knows that I am trying to throttle it back, LOL! Creepy stuff!
renice -n 19 -p 170178
renice -n 19 -p 170288
renice -n 19 -p 170332
renice -n 19 -p 170333
renice -n 19 -p 170334
I DO like the ability to quickly search my files, especially the contents of my files, but I am not sure if it is worth the fire risk.
OK I did a little more digging as of 12:25 1/23/2022...
I ran the tracker status command on a specific .xls file and with no argument and got:
user@computer:~$ tracker status /home/user/Documents/Win7Backup/D_Drive/user/Libraries/Documents/Biz/Books/2017Tax.xls
Currently indexed: 170422 files, 13538 folders

user@computer:~$ tracker status
Currently indexed: 170422 files, 13538 folders

Then top shows:
