Please CC me on replies. A admin accidentally deleted the swap line from the fstab file. We mount the swap filesystem via labels. However, there seems to be no way to list the label on an existing swap partition, via the command line swap tools (mkswap, swapon/off, etc) Is this blindness on my part, or should there be an analog to e2label for swap partitions? --Jason ^ permalink raw reply [flat|nested] 3+ messages in thread

There's this cheesy way to get it: # dd if=swapfile bs=4k count=1 | xxd -a 1+0 records in 1+0 records out 4096 bytes (4.1 kB) copied, 6.2589e-05 s, 65.4 MB/s 0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................ * 0000400: 0100 0000 ffff 0000 0000 0000 f209 fce3 ................ 0000410: 7bc9 486d ac86 5d63 af25 3c99 466c 6173 {.Hm..]c.%<.Flas 0000420: 6853 7761 7000 0000 0000 0000 0000 0000 hSwap........... 0000430: 0000 0000 0000 0000 0000 0000 0000 0000 ................ * 0000ff0: 0000 0000 0000 5357 4150 5350 4143 4532 ......SWAPSPACE2 You can see it is marked as SWAPSPACE2. The label is FlashSwap.
