Hi guys,
Found one interesting bug, about big kick-start/preseed file.
I want to deploy MOS with 10 Ceph nodes.
1. Success story: On 5 of them I have only 5 disks, each disk has additional partition for journal. Provisioning of these nodes works fine.
2. On node (by my fault) has 25 disks and journal in a file. I just forgot create additional partition. Provision of this node works fine too.
3. Unsuccessful: On other 4 nodes I have 25 disks with additional partition for ceph-journal.
When i started to search for solution i found that:
1. Preseed file in first case was: ±80kb.
2. In second case: 110kb.
3. In third case: 155kb.
It seems that we have linux limitation of length of the one string.
When I have removed 4 drives from those unsuccessful nodes, provision work fine.
So guys, it seems that we should create something like "helper.sh" that will be downloaded during the provision. This "helper" should command-line parameters like:
/tmp/part_create.sh 1:10GB:xfs:/var/lib/ceph/osd-1/journal 2:100GB:xfs:/var/lib/ceph/osd-1
It is my vision, how to fix this. |

So guys, it seems that we should create something like "helper.sh" that will be downloaded during the provision. This "helper" should have short command-line parameters like this:
/tmp/part_create.sh 1:10GB:xfs:/var/lib/ceph/osd-1/journal 2:100GB:xfs:/var/lib/ceph/osd-1
