(please excuse my windows admin background!)
On an ESX 3.0.2 server, how can I find the size of a filesystem or partition like root or var or whatever the default ones are that exist when you install ESX 3.0.2 with the default selections? Also, how can I find the used space and free space in them? I am just looking for the commands to run from the service console. What is the difference between a filesystem and a partition in Linux? (sorry again!)
Try df or vdf. man df to get the manual pages. Filesystem and partiion in linux are the same as in Windows. Filesystems are ext2/ext3 vs ntfs/fat. Partition is just part or slice of disk.
Thanks!
Is there also a command to change the size of a filesystem or partition?
Here's a few useful commands to use on the Service Console related to disk and file info...
• "df -h" will show drive and space information (no vmfs volumes though). The -h will tell it to show the disk information in human-readable format, e.g. 1.9G instead of 1967156
• "fdisk -l" will display information about disk partitions
• "cat /proc/scsi/scsi" will show SCSI device information
• "vdf -h" is a VMware specific command and will show vmfs volumes and space. The -h will tell it to show the disk information in human-readable format, e.g. 1.9G instead of 1967156
• "ls -l" will show detailed file information including size, permissions, owner, last modified
• "ls -sh" will show basic file and size information
• "du -h" to show total disk usage for a directory
• Finding text inside a file, ie. search for the string tool.syncTime in all the vmx files:
o find -name '*.vmx' -type f -print0 | xargs -0 grep "tools.syncTime" /
• Finding files, ie. search for all virtual disk files that have -flat.vmdk in the filename:
o find -iname "*-flat.vmdk" -ls

Same as Windows. You have to blow it away and recreate it. However, you can't do it on c: drive or root (or other system directories.) You can use a live cd such as gparted. For esx, just re-install it. It will be faster to rebuild it than download/burn a live cd and learn how to use it.
