Hello, while going through "Re: [DRBD-user] online shrinking errors / Centos5 drbd 8.3.1 from Testing", I was asking myself: How is meta data in general handled with resize ? Lets assume device like shown in the graphics (where d1/2/3 are data areas and m is the meta part). 1) internal meta data [ d1 | d2 | d3 | m ] 1a) grow Is the meta data moved to the end of the device ? [ d1 | d2 | d3 | d4 | m ] Or is meta data kept in the middle ? [ d1 | d2 | d3 | m | d4 ] 1b) shrink Is the meta data moved forward to device ? [ d1 | d2 | m ] Or is meta data truncated ? (this is the correct one, seems to be answered by the e-Mail) [ d1 | d2 | | m ] 2) external meta data (assuming the meta data device "just as large as it needs to be" according to http://www.drbd.org/users-guide/ch-internals.html#s-external-meta-data) [ d1 | d2 | d3 ] [ m ] 2a) grow Do I have to resize the meta device before resize of the device ? Is meta data automatically resized ? 2b) shrink Same questions as above It would be great if this would be outlined in the admin guide. Thanks, Robert
