specingIs there a speed-limited version of dd?00:55
specingI'd like to copy one file over another, but slowly00:55
gnarfacewhy would you need to do that?01:00
specingto prevent the damn ssd using slc cache to pretend that it is fast01:03
jaromilhi everyone! a while ago we have announced the https://LEDGERproject.EU a 200k EUR equity-free fund that among other goals leverages Devuan uses for "human-centric solutions" by funding teams with a clear goal and 9 months to dedicate to its realisation. Today we have an on-line public "webinar" basically a video call open to future applicants to ask questions and get help in packing a submission.09:17
jaromilAnyone interested is very welcome! infos here https://twitter.com/DevuanOrg/status/1098491167338057728 this is a great opportunity to get public money in good use in Europe, I hope many of you consider applying!09:17
tyilspecing: make a while loop call dd every 10 seconds, and write only a couple bytes each time around and set the start offset by the number of bytes you wrote already11:44
specingtyil: hmm, that would work as well12:35
jyrispecing: check this thread https://unix.stackexchange.com/questions/48138/how-to-throttle-per-process-i-o-to-a-max-limit13:51
jyridd will write at bus/device speed, even if you sleep between writes it will write the amount of bytes at max13:54
r3bootThat kind of depends how you configure the bs parameter; If you copy byte-by-byte, the overhead per byte can lead to dd not saturating the bus13:57
specingshiny, btrfs errors on devuan install image14:17
jyrir3boot: if you copy byte-by-byte and sleep even 1/10th of second between every byte you will never hit the problem with the overhead :D14:40
r3bootSure, but you will also never ever be able to write at bus speed then ;)14:41
roo^yif the bus speed drops below 50 mph, not even neo can stop it from exploding16:42
fsmithredIs that a European bus or an African bus?17:11
josuahI'm gonna install devuan at work's vmware...21:05
josuahI wish it was qemu or xen (or bare metal if you ask me) but vmware will be better than nothing :)21:05
