Hmmm, I have to disagree with 'too many services' What do you mean, there is a process for each osd, mon, mgr and mds. There are less processes running than on a default windows fileserver. What is the complaint here? 'manage everything by your command-line' What is so bad about this? Even microsoft is seeing the advantages and introduced power shell etc. I would recommend hiring a ceph admin, then you don't even need to use the web interface. You will have voice control on ceph, how cool is that! ;) (actually maybe we can do feature request to integrate apple siri (not forgetting of course google/amazon talk?)) 'iscsi' Afaik this is not even a default install with ceph or a ceph package. I am also not complaining to ceph, that my nespresso machine does not have triple redundancy. 'check hardware below the hood' Why waste development on this when there are already enough solutions out there? As if it is even possible to make a one size fits all solution. Afaiac I think the ceph team has done great job. I was pleasantly surprised by the very easy to install. Just with installing the rpms (not using ceph-deploy). Next to this, I think it is good to have some sort of 'threshold' to keep the wordpress admin's at a distance. Ceph solutions are holding TB/PB of other peoples data, and we don’t want rookies destroying that, nor blame ceph for that matter. -----Original Message----- From: Alex Gorbachev [mailto:ag@xxxxxxxxxxxxxxxxxxx] Sent: dinsdag 16 januari 2018 6:18 To: Massimiliano Cuttini Cc: ceph-users@xxxxxxxxxxxxxx Subject: Re: Ceph Future Hi Massimiliano, On Thu, Jan 11, 2018 at 6:15 AM, Massimiliano Cuttini <max@xxxxxxxxxxxxx> wrote: > Hi everybody, > > i'm always looking at CEPH for the future. > But I do see several issue that are leaved unresolved and block nearly > future adoption. > I would like to know if there are some answear already: > > 1) Separation between Client and Server distribution. > At this time you have always to update client & server in order to > match the same distribution of Ceph. > This is ok in the early releases but in future I do expect that the > ceph-client is ONE, not many for every major version. > The client should be able to self determinate what version of the > protocol and what feature are enabable and connect to at least 3 or 5 > older major version of Ceph by itself. > > 2) Kernel is old -> feature mismatch > Ok, kernel is old, and so?

As a technical note, we ran into this need with Storcium, and it is pretty easy to utilize UID indicators using both Areca and LSI/Avago HBAs. You will need the standard control tools available from their web sites, as well as hardware that supports SGPIO (most enterprise JBODs and drives do). There's likely similar options to other HBAs. Areca: UID on: cli64 curctrl=1 set password=<password> cli64 curctrl=<controller #> disk identify drv=<drive ID> UID OFF: cli64 curctrl=1 set password=<password> cli64 curctrl=<controller #> disk identify drv=0 LSI/Avago: UID on: sas2ircu <controller #> locate <enclosure #>:<slot #> ON UID OFF: sas2ircu <controller #> locate <enclosure #>:<slot #> OFF HTH, Alex Gorbachev Storcium > I guess this kind of feature are quite standard across all linux > distributions. > > The management complexity can be completly overcome with a great Web > Manager. > A Web Manager, in the end is just a wrapper for Shell Command from the > CephAdminNode to others. > If you think about it a wrapper is just tons of time easier to develop > than what has been already developed. > I do really see that CEPH is the future of storage.
