I'm running a CentOS 4.6 final box with a second drive array (raid 1, the mount is
/mnt/raid, as listed below in my nagios warning) that uses ntfs-3g as the file system. My nagios warnings just went off saying that I'm running out of inodes but still have 10% of the drive space available (I am aware this is common).
However I'm possibly mis-understanding the problem since when I do a
df -hi, my output seems to indicate I only have a pending drive space issue. Also, NTFS does not use inodes, so what gives?
df -hi output
[root@images ~]# df -hi Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/VolGroup00-LogVol00 9.1M 190K 8.9M 3% / /dev/hda1 26K 39 26K 1% /boot none 127K 1 127K 1% /dev/shm /dev/sda1 52M 141K 52M 1% /mnt/raid
df -h output:

And here's my Nagios warning:
DISK WARNING - free space: /mnt/raid 52452 MB (10% inode=99%):
The warning says free space, but 52GB is plenty at 10% available. What concerns me is the
inode=99% part. Doesn't this mean Nagios is reporting that 99% of inodes on
/mnt/raid are being used?
/mnt/raid is NTFS, so I don't think it even uses inodes? Correct?
