Open Stack

Hi Yatin,



Sdfs filesystem does not have a device node (like /dev/sda). We think Swift 
is complaining fort hat reason.



FYI,

Hi Yatin,

I checked volume. Device is mounted. When I unmount device, I get error 
message.

Hi Mehmet,



Just check if the volume is mounted.



then, umount the volume and check if those directories no more seen on 
system.



also, if you are following swift saio, check the rsync settings.



check /srv permissions and check if path  /sda1/805/ exists.



Regards,

Yatin

Hi Yatin,

I stoped swift services after deleted ring files. and I created new rings 
but ı get same error message.
I apply the following steps.
swift-ring-builder object.builder create 10 3 1
swift-ring-builder object.builder add r1z1-192.168.56.34:6010/sda1 1
swift-ring-builder object.builder add r1z2-192.168.56.34:6020/sda2 1
swift-ring-builder object.builder add r1z3-192.168.56.34:6030/sda3 1
swift-ring-builder object.builder rebalance
swift-ring-builder container.builder create 10 3 1
swift-ring-builder container.builder add r1z1-192.168.56.34:6011/sda1 1

Hi Mehmet,



Under 'swift-ring-builder' you should use different directories/device-name, 
as sda1, sda2 and sda3.

Yatin
