The Fedora 21 mass rebuild took about 40 hours this time. This a bit of improvement over last time and we have more packages now. Distribution of builds: (all times my local time, Month/Day/Hour) Jun 06 16 82 Jun 06 17 183 Jun 06 18 365 Jun 06 19 370 Jun 06 20 385 Jun 06 21 374 Jun 06 22 363 Jun 06 23 365 Jun 07 00 380 Jun 07 01 378 Jun 07 02 350 Jun 07 03 409 Jun 07 04 447 Jun 07 05 453 Jun 07 06 345 Jun 07 07 294 Jun 07 08 312 Jun 07 09 372 Jun 07 10 314 Jun 07 11 421 Jun 07 12 474 Jun 07 13 393 Jun 07 14 310 Jun 07 15 251 Jun 07 16 284 Jun 07 17 362 Jun 07 18 327 Jun 07 19 358 Jun 07 20 516 Jun 07 21 409 Jun 07 22 350 Jun 07 23 222 Jun 08 00 231 Jun 08 01 273 Jun 08 02 271 Jun 08 03 319 Jun 08 04 317 Jun 08 05 281 Jun 08 06 276 Jun 08 07 266 Jun 08 08 273 Jun 08 09 190 Total packages rebuilt: 13929 Packages that failed: 1298 Please see http://ausil.fedorapeople.org/f21-failures.html for a list of failed builds. Also, bugs are being filed against all the failed builds (including logs) for maintainers. The rebuilds should land in today's rawhide (syncing out now). We are going to be branching Fedora 21 from rawhide in just about a month: 2014-07-08 so it would be great if we could get things all cleaned up before then.
