This is a multi-part message in MIME format. --------------060409060909070106030504 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against the oVirt server database, please run select sds.id, ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage=ssc.id where sds.id='1083422e-a5db-41b6-b667-b9ef1ef244f0'; You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount list that you see that it is mounted, the mount itself should contain a directory named as the uuid of the master domain, let me know the result.

select sds.id, ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage=ssc.id where sds.id='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount list that you see that it is mounted, the mount itself should contain a directory named as the uuid of the master domain, let me know the result.

Hi Limor, 1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them? 2) can you send the printout of 'tree /rhev/data-center/' 3) how many domains are attached to your DC, and what type are they(ISO, export,data) and (The DC is nfs right)? Thanks, Yeela ----- Original Message -----

Thank you very much for your reply. I ran the commands you asked (see below) but a directory named as the uuid of the master domain is not mounted. We tried to restart the VDSM and the entire machine it didn't help. We succeeded to manually mount " /home/BO_Ovirt_Storage" to a temporary directory.

Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against the oVirt server database, please run
select sds.id , ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage= ssc.id where sds.id ='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount list that you see that it is mounted, the mount itself should contain a directory named as the uuid of the master domain, let me know the result.
Tal.

Hi Limor, 1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them? 2) can you send the printout of 'tree /rhev/data-center/' 3) how many domains are attached to your DC, and what type are they(ISO, export,data) and (The DC is nfs right)?
Thanks, Yeela

Thank you very much for your reply. I ran the commands you asked (see below) but a directory named as the uuid of the master domain is not mounted. We tried to restart the VDSM and the entire machine it didn't help. We succeeded to manually mount " /home/BO_Ovirt_Storage" to a temporary directory.

Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against
oVirt server database, please run
select sds.id , ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage= ssc.id where sds.id ='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount list that you see that it is mounted, the mount itself should contain a
1083422e-a5db-41b6-b667-b9ef1ef244f0 the directory
named as the uuid of the master domain, let me know the result.

Hi Limor, 1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them? 2) can you send the printout of 'tree /rhev/data-center/' 3) how many domains are attached to your DC, and what type are they(ISO, export,data) and (The DC is nfs right)?
Thanks, Yeela

Thank you very much for your reply. I ran the commands you asked (see below) but a directory named as the uuid of the master domain is not mounted. We tried to restart the VDSM and the entire machine it didn't help. We succeeded to manually mount " /home/BO_Ovirt_Storage" to a temporary directory.

Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against
oVirt server database, please run
select sds.id , ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage= ssc.id where sds.id ='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount list that you see that it is mounted, the mount itself should contain a
1083422e-a5db-41b6-b667-b9ef1ef244f0 the directory
named as the uuid of the master domain, let me know the result.

Hi Limor, 1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them? 2) can you send the printout of 'tree /rhev/data-center/' 3) how many domains are attached to your DC, and what type are

Thank you very much for your reply. I ran the commands you asked (see below) but a directory named as the uuid of the master domain is not mounted. We tried to restart the VDSM and
entire machine it didn't help. We succeeded to manually mount " /home/BO_Ovirt_Storage" to a temporary directory.

Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against
1083422e-a5db-41b6-b667-b9ef1ef244f0 the
oVirt server database, please run
select sds.id , ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage= ssc.id where sds.id ='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount
that you see that it is mounted, the mount itself should contain a directory named as the uuid of the master domain, let me know the result.

the vdsm.log.44.xz is exactly what I needed. It looks like your storage should be fine. please try 'rm -rf /rhev/data-canter/*' and then reboot the host. let me know if it solves the problem. and if not, attach the new logs. ----- Original Message -----

Thank you very much for your reply.
I see that the problem appears in vdsm.log.44.xz but doesn't appear in vdsm.log.45.xz
*[wil@bufferoverflow vdsm]$ xzcat vdsm.log.45.xz | grep StoragePoolMasterNotFound | wc -l* *0* *[wil@bufferoverflow vdsm]$ xzcat vdsm.log.44.xz | grep StoragePoolMasterNotFound | wc -l* *52*
so I hope the source of the problem is in one of them (attached).

Hi Limor, 1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them? 2) can you send the printout of 'tree /rhev/data-center/' 3) how many domains are attached to your DC, and what type are

Thank you very much for your reply. I ran the commands you asked (see below) but a directory named as the uuid of the master domain is not mounted. We tried to restart the VDSM and
entire machine it didn't help. We succeeded to manually mount " /home/BO_Ovirt_Storage" to a temporary directory.

Hi Limor, First we should probably start with checking which mount is the master storage domain that appears as not found, this should be checked against
1083422e-a5db-41b6-b667-b9ef1ef244f0 the
oVirt server database, please run
select sds.id , ssc.connection from storage_domain_static sds join storage_server_connections ssc on sds.storage= ssc.id where sds.id ='1083422e-a5db-41b6-b667-b9ef1ef244f0';
You can run this via psql or a Postgres ui if you have one. In the results you will see the storage connection in the format of %hostname%:/%mountName%, then in the VDSM server check in the mount
that you see that it is mounted, the mount itself should contain a directory named as the uuid of the master domain, let me know the result.
