Investigate issues with disks more than 1TB

[rgayon]

Uploads seem to stall when reaching 1TB on a 1.5TB disk

This would be the pid of the underlying dcfldd, when the upload is stalling

# cat /proc/26925/io 
rchar: 1041529571228
wchar: 1041530654463
syscr: 496646
syscw: 498828
read_bytes: 1023014080512
write_bytes: 1019904
cancelled_write_bytes: 0

I faced the same issue:

sudo cat /proc/12895/io
rchar: 1041529571228
wchar: 1041530654463
syscr: 496646
syscw: 498828
read_bytes: 1041529704448
write_bytes: 1019904
cancelled_write_bytes: 0

Pushing the disk via a gsutil stream transfer worked for me, example:

dcfldd if="/dev/[DEV_NAME]"  hashlog=image.hash hash=md5,sha1 bs=2M \
        conv=noerror hashwindow=128M | gsutil  cp  -  [Archived_Disk_Path]
