every now and then, in ubuntu 18.04 , also when i only have like 1 tab in chrome, and libre office writer open, on my acer E17, i5, 8 gb ram, 1 tb wd hdd, it becomes unusable! The hard disk starts working and does not stop. A click to close the browser can take minutes to work, or even not at all. alt tab, nothing... just a hard working hdd
I found ioshop or something to system usage, but could not install it yet. ctrl-t does nothing, just hdd at work sound.
this happens every week at least 1 time, no matter what i was doing with the laptop.
anyone encountered this, any solutions?
update: it has been an hour now, even the mouse is unusable, move a bit and wait where it goes... click on x for firefox did nothing other usefull info: Excessive hard disk activity and: Continuous disk activity since upgrading to Ubuntu 18.04
update 2; hdd does not stop, going to power button laptop down...
Update 3 : sudo iotop , shows a clean lean machine, almost 0%, sometimes a few entry's peak at 0,x up to 6% , shortly and drop to zero again. And this is correct, the laptop is smooth fast and responsive. UNTIL out of no where(?) the hdd activity goes wild.
Update 4, i can not 'uncouple' the /dev/dsa3 hdd that contains ubuntu. fsck warns me that a check of the disk WILL cause heavy damage
touch /forceheck, also with sudo, can not be done, /dev/dsa3/ is coupled...
Can not UN-couple sda3... udisk error quark 14 , target is busy
