disk 100% busy

Hello,

Since today i have this process jbd2 using all my disk utilization, how can i fix this ?
I use debian + ispconfig 3, i followed the perfect server tutorial, i have 400 days uptime it's the first time i face this issue.


Thank you.

 

Hi

Please paste the output of

 

If you find the process of jbd2 then edit your /etc/fstab as for example

Add noatime as shown above.

 

output of ps -ef|grep jbd2

Code:

root       298     2  0 mai19 ?        00:00:02 [jbd2/sda2-8]
root      1785     2  0 mai19 ?        00:01:53 [jbd2/sda3-8]
root     22697 21180  0 14:38 pts/0    00:00:00 grep jbd2

i noticed this happens when i write lots of data in mysql, maybe i need to upgrade to ssd.
for the noatime option, there is no downside to use it ?

Thank you.

 

noatime means that the access time of files is no longer stored.
This can decrease hdd acrivity when you have a lot of disk access.
