How do you delete a vault
Up to Dispersed Storage Users
Posted by
Hello Rodney,
To answer your question, even though the current release of the software contains the protocol messages and handlers necessary to remotely delete a vault, our release doesn't come with a command line utility to remotely delete vaults. Therefore the process of deleting a vault must be done manually by for each server deleting the directories with the name of the vault id, they will be located in a folder similar to:
/opt/dsnet-slicestor/output/slicestor/descriptors/{VAULT-ID}
/opt/dsnet-slicestor/output/slicestor/stores/{VAULT-ID}
Note that the location of this folder can vary depending on your configuration. I hope this information is helpful.

When I’m creating vault the following error is occurring. Is there any issue with “vault-descriptor.xml"? if yes
Can I have example file of “vault-descriptor.xml for single slicer and 8x6 slicer" ?
./dsnet-create-vault --name="test" --descriptor="/opt/dsnet-accesser/conf/vault-descriptor.xml"
Error creating vault on access server
Unable to parse vault descriptor
This error usually appears when the "dsnet-create-vault" script cannot parse the host address of the slicestors (the "IP_HERE" values on the sample vault descriptor below) because of a syntax error. Use IP addresses for these vaues. The sample vault descriptor below is for an 8-loose-2 dsnet, which is the tested and supported configuration. For a 1-loose-0 vault descriptor you would use the same vault descriptor but with only one "<vault:slice-store kind="SliceStore" referral="remote">" section (removing the remaining 7).
Please post the vault descriptor file you are using, which will help us better troubleshoot your problem.

Please verify and let me know the issue.
Thanks in advance,

Hi Kiran,
You need to "close" the vault:vault tag at the end of that vault descriptor file. It needs a "</vault:vault>" at the end after the vault:slice-store section, as shown below. Let us know if you face any other issues.

Hi,
Thanks a lot Vicente. Now I'm able to create vault.
But sitll have some issue in mounting iSCSI traget on the client. The mount process is taking to long time and also after mount, disk is not visiable.
I have followed the below process to mount the iSCSI taget.
#Step 1
[root@test ~]# iscsiadm --mode node --targetname iqn.2008-06.com.test.dc:test --portal 10.176.87.22:3260 --login

[root@test ~]# iscsiadm -m session -i
iscsiadm version 2.0-742

Please advice. Your help is highly appreciated,

[Careful with the instructions below as they reformat the partition and cause the loss of data!]
It seems like the sdb device has been created. Now you will need to create a partition and format it. Something similar to this:
# fdisk /dev/sdb
This will present you with a "prompt" menu. Type "m" for info. But basically you will want to type "n" to "add a new partition", then "p" for "primary partition", then "1" for the partition number. Choose the defaults for "First cylinder" and "Last cylinder" by just typing "Enter". Then type "w" to write to the partition table.
Then you will need to format it:
# mke2fs -j /dev/sdb1
Once this is finished (might take some time depending on the size of your vault), you need to mount:
# mount /dev/sdb1 <mount-point>
Where <mount-point> is the location of your mount point. For example, /mnt/myvault/
Hope this helps! Let us know.
Thanks a lot Vicente. Your help is highly appreciated.
I have reinstalled everything but still have some issue in mounting iSCSI target on the client.
I think the issue with login username password when login iSCSI target. Can you please tell me how does Clever safe manages the username & password when login iSCSI target.
-Thanks,
