Setup Elastic Drive in Jeos/VMWare

Sometimes if you try to run Elastic Drive

root@khazJeosED:/opt/e# sudo elasticdrive /etc/elasticdrive.ini -d

and get following error:

Traceback (most recent call last): File "/usr/bin/elasticdrive", line 5, in pkg_resources.run_script('ElasticDrive==0.4.1-FREE-5-r54', 'elasticdrive') File "build/bdist.linux-i686/egg/pkg_resources.py", line 448, in run_script File "build/bdist.linux-i686/egg/pkg_resources.py", line 1173, in run_script File "/usr/bin/elasticdrive", line 175, in

it means that local time should be adjusted to comply Amazon S3 requirement (max difference might be 10 minutes).

Extract time part from response 2008-01-23T18:47:06Z minus 5 hours, and use it to set time in sync. Run following command:

date --set="2008-01-23 13:47:43"

run again

root@khazJeosED:/opt/e# sudo elasticdrive /etc/elasticdrive.ini -d

if no errors, lets check it all goes well

#ps aux

let's mount filesystem

root@khazJeosED:/opt/e# sudo mount -o loop /fuse2/ed0 /s3
mount: you must specify the filesystem type

this might mean that you need to run

#mke2fs -b 4096 /fuse2/ed0

mke2fs 1.40.2 (12-Jul-2007)
/fuse2/ed0 is not a block special device.Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
65536 inodes, 65536 blocks
3276 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=67108864
2 block groups
32768 blocks per group, 32768 fragments per group
32768 inodes per group
Superblock backups stored on blocks:

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 33 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.
root@khazJeosED:/opt/e#


now we can run the previous command:

root@khazJeosED:/opt/e# sudo mount -o loop /fuse2/ed0 /s3
root@khazJeosED:/opt/e#

Let check it went fine:

root@khazJeosED:/opt/e# df -h
