IM doesn't read multi-devices in SDS Device List

Hi Taizo,

Try to put the list of the devices within quotation marks:

"/dev/sdb,/dev/sdc"

Cheers,

Hi Pawel,

Thank you for your reply.

With double quotation marks, IM installation was successful.

But after adding more devices in the SDS Device List, IM installtion to an existing system didn't allocate the new devices.

1. e.g

SDS Device List for the fisrt installation "/dev/sdb,/dev/sdc"

SDS Device List for the installation to the existing sys "/dev/sdb,/dev/sdc,/dev/sdd"

The topology IM displays after the updated csv file was uploaded has /dev/sdd.

After the installtion, /dev/sdd was not added.

/dev/sdd was successfully added after I once uninstalled the existing sys.

If this behavior is known and true to this ScaleIO version, IM can not be used to add devices, Sure we can just add devices via GUI or CLI though.

Many thanks,

Taizo

Hi,

Additionally, I am trying to install ScaleIO with multiple-SDSs.

This time 3 SDS nodes with 2 SDSs per node.

MDMs also reside on the same nodes.

But it failed with the following error at the configure phase.

same errors on 2 other nodes Command Failed: "Could not add SDS 10.0.0.2 to Protection Domain default due to: Device already added to another SDS. To override, add the specific sds device with force device takeover

My CSV file is like this

...Is MDM/TB,MDM IPs,Is SDS,SDS Name,SDS-SDS Only IPs,SDS-SDC Only IPs,SDS Device List....

...Master,10.0.0.2,Yes-1,master-sds1,10.0.1.2,10.0.2.2,"/dev/sdb",...

...Master,10.0.0.2,Yes-2,master-sds2,10.0.1.2,10.0.2.2,"/dev/sdc,/dev/sdd",...

...Slave,10.0.0.3,Yes-1,slave-sds1,10.0.1.3,10.0.2.3,"/dev/sdb",...

...Slave,10.0.0.3,Yes-2,slave-sds2,10.0.1.3,10.0.2.3,"/dev/sdc,/dev/sdd",...

...TB,10.0.0.4,Yes-1,tb-sds1,10.0.1.4,10.0.2.4,"/dev/sdb",...

...TB,10.0.0.4,Yes-2,tb-sds2,10.0.1.4,10.0.2.4,"/dev/sdc,/dev/sdd",...

I feel sorry for many questions but my team mates could not also find where are wrong.

Many thanks,

Taizo

Hi Taizo,

To be completely honest, I have never tried to add a device using IM CSV file - I would say the proper way of doing it would be the GUI or scli.

Regarding adding multiple SDS - have you followed the steps mentioned in the Deployment Guide? See:

When extending a node on which there are multiple SDS, you must first set add.sds.with.force.on.next.run = true, as described in “Adding SDS devices that were used in a previous ScaleIO system” on page 68.

Please add this option to the gateway properties file and see if that helped.

Thank you,

Pawel

Hi Pawel

Sorry for the late reply.

Speaking of IM installation with multiple-SDSs adn Multiple SDS devices, it was successful. "add.sds.with.force.on.next.run = true" was needed even for a totally new environmet.

As you advise, we will not use IM for topology updates. We will use GUI and CLI not only to add and remove compoments but also devices.

Much appreciated,

Taizo
