Elasticsearch and inodes

[granier]

Hi,

In configuration system https://www.elastic.co/guide/en/elasticsearch/reference/master/file-descriptors.html there is a point about the number of files that can be opened by Elasticsearch.

But there is no item about inodes number, is there a requirement, advice about this number ?

Sincerly,

Hi,

I've never encountered any advice about the number of inodes in the documentation, but with modern filesystems I don't think that You'll have to worry about them. Example from one of our warm nodes (RHEL7 with XFS filesystem):

[root@xxxdb07 ~]# df -i /var/lib/elasticsearch/
Filesystem                               Inodes IUsed      IFree IUse% Mounted on
/dev/mapper/VolGroup01-LogVol_esdata 2013265920  9580 2013256340    1% /var/lib/elasticsearch
[root@xxxdb07 ~]# df -h /var/lib/elasticsearch/
Filesystem                            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup01-LogVol_esdata  3.8T  2.4T  1.4T  64% /var/lib/elasticsearch
