[Evms-cluster] Severe EVMS Volume problems

[Bjoern M. <bm...@tu...>]

Hello all,

we have some major timecritical problems with our evms setup:

We have 2 machines running heartbeat evms cluster, sharing a private 
evms container between them, which consists of a OPEN-E (www.open-e.com) 
iscsi-device which has been mounted via open-iscsi under Linux 2.6.16.3.

The OPEN-E-Device consists of a small Linux exporting a 
Areca-Raid-Volume via ISCSI to clients.

The problem began after updating the firmware on the Areca-Controller, 
while the iscsi device (/dev/sdb on the servers) was mounted on server1.

After the firmware update the device /dev/sdb had lost its partition table:

scsi5 : iSCSI Initiator over TCP/IP, v.0.3
   Vendor: iSCSI     Model: TARGET            Rev: 0
   Type:   Direct-Access                      ANSI SCSI revision: 04
sdb : very big device. try to use READ CAPACITY(16).
SCSI device sdb: 20507721728 512-byte hdwr sectors (10499954 MB)
sdb: Write Protect is off
sdb: Mode Sense: 77 00 00 08
SCSI device sdb: drive cache: write back

SCSI device sdb: drive cache: write back
  sdb: unknown partition table
sd 5:0:0:0: Attached scsi disk sdb
sd 5:0:0:0: Attached scsi generic sg1 type 0

We restored the partition table manually with parted, but evms does not 
recognize the cluster volume anymore.

How can we reactivate the cluster volume WITHOUT losing data?

We are willing to pay for fast support, we need urgent help

Attached is the output of evmsn -d debug, running with admin_mode=yes
