I use MRTG 2.16.4 with RRDTool 1.4.3 for about 30000 targets, and I have
long-time troubles with blocked system while kernel do SYNC of all cached
I have MRTG on separated partition with EXT3.
There is mount options: ext3 defaults,noatime,commit=120 1 2
I use Linux CentOS 5.6 with kernel 2.6.18-238.12.1.el5.
Hardware is 2x XEON5160 at 3.00GHz, 8GB RAM, 2x 15000RPM HDD.
Can somebody help me with speed-up of SYNC?
Which filesystem will be better than EXT3 for MRTG?
Which other options than "noatime,commit=120" will be helpful?
Maybe other kernel will be better?
Thanks for ideas.
