boot: why wait for a removable SCSI disk?












0















I have turned off quiet and splash to see why my boot takes so long on my new SSD.



I see the following at 3.xx seconds:



sd 4:0:0:0: Attached scsi generic sg2 type 0
sd 4:0:0:0: [sdb] Attached SCSI removable disk


then it sits there for 30 seconds and at 33.xx seconds:



Begin: Waiting for suspend/resume device ... Begin: Running /scripts/...
random: fast init done


I have only one disk (and this is only removable with a screw driver), I imagine it could be waiting for a card in the SD card reader?



Here is the extract from dmesg:



[    3.172236] sd 4:0:0:0: Attached scsi generic sg2 type 0
[ 3.177895] sd 4:0:0:0: [sdb] Attached SCSI removable disk
[ 33.999093] random: fast init done


And I noticed more in my screenshot (not in the dmesg output):
photo from boot screen

          The warning in the screenshot appears to be the culprit:



          WARNING: Failed to connect to lvmetad. Falling back to device scanning.
