Good day! I am working on a robust backup script for RBD and ran into a need to reliably determine start and end snapshots for differential exports (done with rbd export-diff).
I can clearly see these if dumping the ASCII header of the export file, e.g.: iss@lab2-b1:/data/volume1$ strings exp-tst1-spin1-sctst1-0111-174938-2016-cons-thin.scexp|head -3 rbd diff v1 auto-0111-083856-2016-tst1t auto-0111-174856-2016-tst1s It appears that "auto-0111-083856-2016-tst1" is the start snapshot (followed by t) and "auto-0111-174856-2016-tst1" is the end snapshot (followed by s). Is this the best way to determine snapshots and are letters "s" and "t" going to stay the same? Best regards, -- Alex Gorbachev Storcium
