High read/write in alfresco metadata vol

Question asked by dipti on Dec 11, 2015
Hi All,

We have 2 alfresco setups on 2 separate Linux servers sharing their DB and File system.
The application is active using only one alfresco at a time.
From last 15 days,we are facing issue on high read/write in alfresco metadata volume as seen below:

As seen above the vol alfresco_metadatavol is showing high read write operations. The alfresco metadata folder has
alf_data and upload folders.
Can you please suggest how can we check why these high operations are happening and why is it so. As when this data is being replicated to DR ,the SRL is reaching 100% in 6-7 working hrs on 6MBps line.
Also the file size of metadata volume has only increased by 5GB only in last 15 days. Whereas the SRL shows of very high delay.
Please suggest.
