Filesystem in ESX 3.5i

[srnagu]

Hi,

I n our ESX 3.5i server, if i issue df, I get below list of filesystems (I havent taken SAN filesys to considerations)

Filesystem Size Used Available Use% Mounted on

unknown 190.1M 128.7M 61.3M 68% /

I'm little confused with the filesys architecture of ESX 3.5i and want to know, what are all these filesys? I have given the contents of each filesys

Yesterday, when we had problem with the server, we were not able to see the 3 filesystems. (out of above 6). After reboot we found all filesys.

Hi,

Since it looked bit confusing, I have uploaded the df output and contents of filesys in excel format.

This will give you a bit of background on some of the partitions - http://www.vm-help.com/esx/esx3i/check_system_partitions.php. The root partition (190 MB) in a RAM drive and the other partititions are mounted below it. Your large one will be your VMFS datastore and the others are bootbank / altbootbank / store and scratch.

In your case

unknown 190.1M 128.7M 61.3M 68% RAM drive

unknown 63.5G 561.0M 63.0G 1% VMFS datastore

unknown 539.8M 252.3M 287.5M 47% store

unknown 47.8M 38.3M 9.5M 80% bootbank

unknown 47.8M 38.3M 9.5M 80% altbootbank

unknown 4.0G 1.0G 3.0G 26% scratch.

thanks a lot

Under any circumstaces, is there any chance for filesystem missing?

Though all the filesys are in the same hard drive, yesterday 3 FAT filesys were missing. Reboot has fixed the issue.

/var/log/messages had SCSI TIME OUT errors like below..

Under normal circumstances it should not disconnect. Might be worth running a hardware check on the server.
