Hi all, I am not on the freebsd-questions list so could you please reply direct. I have recently built a 'samba server' based on FreeBSD 4.0 for one of our customers. All is working perfectly except for the backup. The customer had an Wangdat 3100 in their old Novell server which they asked if we could use. As that amount of data they had to back up would easily fit and the tape drive was working fine with Novell/Arcserve, I said "sure". I spoke too soon. The tape subsystem intermitently works but the majority of the time it reports ther following error. /usr/bin/tar: can't write to /dev/rsa0 : Invalid argument and syslogs: (sa0:sym0:0:6:0): Invalid request. Variable block device requests must be between 53257 and -1 bytes The upper and lower blocksize values seem to vary. I have tried new tapes and doing an 'mt erase' to no avail. device info is: sa0 at sym0 bus 0 target 6 lun 0 sa0: <WangDAT Model 3100 03.0> Removable Sequential Access SCSI-2 device sa0: 4.807MB/s transfers (4.807MHz, offset 8) I have had a trawl through the archives and can find serveral other related questions but no definitive answers. Does anyone have a fix for this or do I just co-incidentally have a sick drive. See you at FreeBSDcon! Thanks in advance Rob Secombe (RS39-AU) Engineering Director Teksupport Pty.
