What will happen if a drive is lost from Raid 1 Pool

@djb Welcome to the Rockstor community.

Glad you like some of what you have seen but re:

@djb

… i simulate a hard disk failure by removing the sata cable. The result was disappointing since the whole storage pool was disappeared,

btrfs does behave differently re something like mdraid but in this case you are with 3.9.1 running potentially very old Rockstor code. You don’t state the exact version but if you have not subscribed to either channel then it’s way old. Our iso is very much due for an update but this will not happen until we have finished our openSUSE move (actually quite close). If you have subscribed to testing then it had it’s last update (3.9.1-16) around 2 years ago which itself was 16 versions on from 3.9.1.0 (iso) which was 4 month prior to that. However the stable channel was last updated 3 weeks ago as of writing. So for the best we have to offer currently you would be strongly advised to try out the stable channel, it also helps us sustain the project’s costs and development.

We are very much in the throws of bringing back the testing channel but it will only be available for our non legacy platform of openSUSE and we are just not quite their yet. But very soon. That change will also bring years of imporovements that have happened in btrfs itself cue to openSUSE backporting curated patches to their otherwise enterprise rated kernel.

@djb

Is there any intention of providing paid professional services for those issues ?

Not until we are fully moved over to openSUSE based offerings as their is simply too much to do until that time. Do appreciate that this is a self funded open source project and very much in active development.

@djb

Let’s say i dont want to give up on Rockstor, even my disappointing experience. What else should i do or try ?

Try upgrading to a more recent versions. And note that if first try the testing channel (up to 3.9.1-16) and then later go to Stable, their was a bug in those later testing updates that will mean your stable update will not actually ‘take’.

yum info rockstor

will then tell you if it’s actually installed or just available as the Web-UI got available and installed confused. But that was in the testing channel. If going from a fresh iso install to stable this does not happen. In any case a simple:

yum update rockstor

sorts it.

Please also take a look at the following forum thread for some background of our more recent developments:

3.9.2-# Stable Channel Changelog

Intro As this thread is starting retroactively in this now long release cycle I’ll first give some context and move to detailing only the most recent releases. The canonical reference for all code changes is in our open source GitHub repo: This is the ‘rockstor’ package origin. This does not include the Rock-on definition files. An attempt is made to keep GitHub Release / git tags in line with package release versions but due to a variety of reasons one can lag the other for short periods. …

and our official docs sub section Update Channels should also help here. I have recently updated that section as well.

Hope that helps.
