<p><font size="2" face="sans-serif">Hi </font><br>
<font size="2" face="sans-serif"> We are trying to fix some eph disk related bugs and also considering our private driver implementation based for eph disk </font><br>
<font size="2" face="sans-serif"> </font><font size="2" face="Default Sans Sarif">I have some questions related "ephemeral_gb" in flavor and nova boot option "--ephemeral", and I failed to find out descriptions in existing documents:</font><br>
<ul style="padding-left: 18pt"><font size="2" face="Default Sans Sarif">1. If I boot a new instance using flavor with "ephemeral_gb" defined as 20 G, and no "--ephemeral" specified, does the new instance have a 20G additional ephemeral disk after booted? </font><br>
<font size="2" face="Default Sans Sarif">2. The flavor has 20 G ephemeral disk defined, but specified two 5 G ephemeral disk through "--ephemeral" option in nova boot cmd, what will happen to the new instance? Get one 20G additional ephemeral? Or two 5 G ephemeral disks instead?</font><br>
<font size="2" face="Default Sans Sarif">3. If the answer to question 2 is "two 5 G ephemeral disks", what will happen if resize this instance to a flavor with "ephemeral_gb" defined as 40 G?</font><br>
<font size="2" face="Default Sans Sarif">4. I think the "ephemeral_gb" in flavor means maximum disk size you can specified, is this understanding correct? </font><br>
<font size="2" face="Default Sans Sarif">5. Also, above question can be applied to swap disk </font></ul>
<br>
<font size="2" face="sans-serif">Asked here and reply guess developers who made this feature can give more info:</font><br>
