Hi, is there a way that I can expand virtual disk space without rebooting VM.
I know that there is a command to recognize the device, but the device is already recognized (such as /dev/sdc), But now I need the OS (Linux) to recognize the additional space without rebooting.
thanks
Re-scan the SCSI Bus to Add a SCSI Device Without rebooting the VM using the following command
echo "- - -" > /sys/class/scsi_host/host#/scan
Hello Curiousmind999,
Once you've changed the disk's size in VMware and did not reboot your server, rescan your SCSI devices as such.
First, check the name(s) of your scsi devices.
$ ls /sys/class/scsi_device/
Then rescan the scsi bus. Below you can replace the '0\:0\:0\:0′ with the actual scsi bus name found with the previous command. Each colon is prefixed with a slash, which is what makes it look weird.
~$ echo 1 > /sys/class/scsi_device/0\:0\:0\:0/device/rescan
That will rescan the current scsi bus and the disk size that has changed will show up.
