SCST is not loaded

[Petr Hosek]

Hi, I'm having issue with SCST that is not loading after reboot.

There were no HW changes, just complete reboot. My ESOS is running as VM in Hyper-V and it's only as lab to test the functionality.

Has anyone had the same problem?

ESOS version 4.2.1

In your kernel log output, it says it can't find the file
"/mnt/vdisks/fs01/vdfs01" -- can you access that file from the root
shell? I assume not since SCST couldn't, so figure out why that is
(perhaps the file system isn't mounted).

There is not a single file inside "/mnt/vdisks/fs01" 

but why it is gone in the first place?

Is the file system mounted at that location?

Hi,

I'm answering just to close this thread after nearly two years.
The issue was in missing array. I'm using now a VMware Workstation with physical disk passthru, so the array is being established via mdadm. The ESOS starting sequence is using mdadm in "/etc/rc.d/rc.mdraid start" command that will trigger mdadm --assemble --scan
The issue is that mdadm config file in /etc/mdadm.conf stays completely untouched even after sync configuration from TUI, so mdadm is not able to reassemble the raid/array.

My workaround was:
- recreate array via TUI (optionally you can run "/etc/rc.d/rc.scst start" to mount FS)

- export runing config in /proc/mdstat via command mdadm --examine --scan >> /etc/mdadm.conf
- check if config was saved into /etc/mdadm.conf file

I hope that this is a permanent workaround and it will not appear again.
