Bug in Syslog?

[miha.adzic]

Hi!

I recently installed Proxmox 4.2 version, setup the disks into RAIDZ-1 on install and went ahead to setup some VMs. Now I tried to change the VM ID but the folder /var/lib/vz/images is empty.

1. Where are the image files located in the case of RAIDZ, or even better, how can I change the ID of a VM?

The Syslog keeps showing me this

Device: /dev/sdf [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 113 to 112

I asked myself is that the temperature of my HDD in Celsius? Torn my machine apart made sure there is more airflow, thinking that the disks in the rack are overheating, removed the rack, added another fan,... and after all that I'm still getting the same messages.

Checked hddtemp /dev/sdf and I get /dev/sdf: WDC WD10EZEX-00BN5A0: 31°C. I know that if I hold my hand on something thats at 100+ °C I'll feel the heat.

2. Is it possible that Proxmox is showing wrong values?

The reason I went into checking the Syslog was my machine randomly reboots. It didn't do this on the old version. I went on to check the disks, RAM, power supply,... Maybe RAM was the case. I can't yet tell since I replaced the RAM just today and no reboot has happened since. I'm doing all of this on an old machine to get to know Proxmox before moving on to the main servers. Anyway thank you for your replies on the two questions above.

to your 1. :

with zfs storage works a little different:

for container there is a zfs subvolume mounted under poolname/subvol-vmid-disk-disknumber
for vms there is a zvol (which is not mounted) under poolname/vm-vmid-disk-disknumber

you can list these with

zfs list

to your 2. question

what you see has nothing to do with pve itself, but are simply the smart values which are returned from the drive
you can see them yourself with:

smartctl -A /dev/sdf

if you have smartmontools installed

sadly, those smart values are poorly standardized, so some vendors use °F, some °C, some are using completely different values.
also, for every smart value, there is the raw and the normalized value (i dont know which one gets checked by smartd)

Hi Dominik!

Thank you for you reply. Is there a way to change the VM ID if youre using ZFS?
I'm trying to change the VM ID from 233 to 243.

Also another question I posted here: https://forum.proxmox.com/threads/raidz-1-replacing-a-dead-drive.27889/

As for the "overheating" I guess I should just ignore what the Syslog shows.

Thank you.

you could manually rename everything (with the vm shudown), or you could
backup and restore to a new vmid
