Hi,

what Hardware do you have?

With "request System storage cleanup" you can clean up some old logs etc.

Maybe run "request System storage cleanup dry-run" first to see what files will be deleted.

[#3]

SRX 1400 is the h/w.

By the way is the current status is ok?e

[#4]

Hi Swati,

What exactly are you looking for in the System storage.

The space looks okay but if you are planning to upgrade the devise to the latest version then the space is not enough and you need to clean up the space for the process.

From the output I couid see that you have around 240 MB space free and for upgrade it will ask you for atleast 260 MB and hence the upgrade would fail.

Guru Prasad

[#5]

will the current memory impact services?

system storage status in this o/p which filesystem needs to be checked from service perspective?

[#6 · Accepted solution]

Hi Swati,

These 2 are the main folders which are used in the devise.

/cf 891M 576M 243M 70% /junos/cf
/var/log 12G 615M 10G 6% /jail/var/log

I can see enough space in that for the devise to function properly.

However as updated in my previous update, if you are planning to upgrade the devise then you need to free us space in the below directory.

/cf                     891M       576M       243M       70%  /junos/cf

the latest image requires 260 MB of space however you only have about 243 MB free.

other than that I do not think there is any issues.

regards,

Guru prasad

what does above directories represent?

100% can cause any impact?

[#8]

Hi,

Folders such as /dev those are a device files "dev=device" , and its ok to be at 100% usage .

Notice if you issue the request storage cleanup command those files will stay at 100% usage because this command mostly will affect the /var /tmp /log .. folders .

/proc/ directory contains a number of directories with numerical names.

These directories are called process directories, as they are named after a program's process ID and contain information specific to that process. So this kind of directory also you cannot manage its usage and it is not affected by the request storage cleanup command .
