amazon web services - EC2 used space increases after resizing volume -


i have followed aws guide expand 8gb volume 16gb.

what have done is:

  1. take snapshot of 8gb volume
  2. create new 16gb volume snapshot
  3. detach 8gb volume ec2 instance, attach 16gb volume ec2 instance

after that, df -h:

filesystem      size  used avail use% mounted on /dev/xvda1       16g   11g  5.3g  67% /

why used size increase 11g? should 8g.

while disk 'bigger', partition has not yet been extended cover new disk space.

use sudo resize2fs /dev/xvda1 extend disk partition include additional space on disk.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
