XOSAN Feedback



  • I get the same error "The attempt to create a VDI failed"



  • Strange. I can take a look remotely if you like, you should create a support tunnel with xoa support tunnel and give me the returned ID 🙂



  • 37485.
    

    The test pool is "santest" there's nothing on there other than the test VM.



  • Thanks I'm in. I'll ask in private message some other info to take a look on the hosts directly.



  • So I installed XS7.2 - clean installation on both hosts. Then did a new install of XOSAN. But the same issue if I attempt to move the disk for the VM I created to the XOSAN SR I get "The attempt to clone the VDI failed." 😞



  • Damn 😕 It's like there is a kind of connection issue between hosts and XOSAN VMs. I'm half-surprised to see that potential problem in an OVH context. I'll try to find the exact problem in detail, please re open a support tunnel.



  • I don't think it really says much but here's part of the log

  • When I check yesterday, I had a transport endpoint not connected error, so the issue is not directly on XenServer, but on GlusterFS that can communicate properly in the XOSAN network.

    But I don't know why, it's like something prevented some packages to work but it's hard to figure it out.



  • It's all working now! 🐵

    The licence cost - is that for as many XOSAN pools as I need controlled from the same XOA or is the cost per pool?



  • It's per pool. Bigger the pool and bigger the disk, cheaper per TiB it is 🙂

    Feel free to continue to play with it and bench it as you need!

    edit: if you want to use an important number of XOSANs, we can always talk about a discount!
