This will be a long post. 8 or 10 months ago I had a hell of a time with amanda, I was useing a perfectly good 1Tbyte baracuda as a holding disk, used by amanda to collect data from client machines so writeing to tape wasn't constricted by the src bandwidth which will shoeshine the tape drive if its not fed data tast enough. But I also use vtapes, not physical ones so shoeshining the tape is not a concern here. But I kept getting CRC errors for the holding disk files, so amanda would redo that disklist entry again, (and again) until it got a good crc. Desparate to find a solution I pulled the data cable off the 1T seagate baracuda and plugged in a 240gig samsung evo 860 SSD I'd originally bought to make a raid6 or 10 /home drive out of. Never done as I now have assembled a 4 pack of 1Tbyte samsung evo 870's for that. I'm using amanda to back up the goodie parts of 5 other machines in addition to this one and was used to a 20 gigabte backup taking 3 or 4 hours in the night. But putting in the SSD, I was amazed that this same sized backup was now taking 20 minutes, and my errors were GONE! There are places where an SMR drive is ok, write once, read mostly is ok, but as a fast in, faster out buffer for amanda sure isn't one of them. So if you have a multi user situation, and servicing this mailing list surely fits in that box, using an SMR drive could very well bite us in the ass with exactly this sort of fantom problems. The write speed for files bigger than the drives buffer can stretch to minutes and requires help from the device driver that the drive may not convey to the driver that it needs help. > While trying to track down the problem, however, I did some > housecleaning, and got rid of the old stuff that I never (or at least > thought I never) use any more.
