perfSONAR User Q&A and Other Discussion

[Hyojoon Kim <>]

Hello, 

It seems my MA machine is running out of disk space, and “df -h” clearly shows that (root “/" is 99% full).

Filesystem            Size  Used Avail Use% Mounted on

lv_root                50G   46G  675M  99% /

lv_data               238G  4.5G  222G   2% /data

I have a more space in “/data”. So I am thinking of (1) migrating all existing data to this new location, and also (2) configure perfSONAR/esmond to store future data to this new location. For (1), I have found this link, and I will probably use instructions in “Migrating Data” to move existing data to some place in “/data” (http://docs.perfsonar.net/multi_ma_backups.html). 

However, I am not sure how to do (2). I have found some instructions for each Cassandra and PostgreSQL, but I’m not sure if this is the right way. Is there an esmond configuration I should touch instead?

(btw, I cannot find "/etc/postgresql/9.5/main/postgresql.conf” in my MA machine.)

Thanks,

Joon
