I have been collecting stats using \_cat/allocation and I noticed that a new cluster showed a lot of disk being used for a few shards. When I checked I found that \_cat/allocation was very different to df. For one node \_cat/allocation gives: 12 51.2gb 956.5gb 1007.8gb 5 esekilx5170 134.138.165.70 70-1 while df for the filesystem allocated to that node gives: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg\_big-lv\_es\_1a 1008G 72M 957G 1% /var/lib/es/data1a It looks like es is reporting the difference between free and total as used and ignoring the reserved free space. Does anyone know if that is the case? /Michael -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You could have multiple node directories though. What's under /var/lib/es/data1a?
