I have the same problem in that case when the drbd starting to sync... I found the solution: In my case it looks like the IBM netcard firmware... You should turn off the tcp segmentation offload with the ethtool... You can watch the state with this command: ethtool -k syncinterface ethtool -K syncinterface tso off Regards, Balázs Lars Ellenberg írta: > / 2007-01-10 11:30:23 +0100 > \ Achim Stumpf: > >> Hi list, >> >> I have compiled drbd 0.7.22 with fedora kernel 2.6.18-1.2239.fc5 as module. >> drbd is running fine actually, but i can't unload the module. >> >> I have rebooted the server first to have a clean start: >> >> [root at clusty6.fra ~]# /etc/init.d/drbd start >> Starting DRBD resources: [ d0 s0 n0 ]. >> [root at clusty6.fra ~]# cat /proc/drbd >> version: 0.7.22 (api:79/proto:74) >> SVN Revision: 2554 build by root at clusty6.fra, 2007-01-05 12:57:19 >> 0: cs:Connected st:Secondary/Primary ld:Consistent >> ns:0 nr:28 dw:28 dr:0 al:0 bm:2 lo:0 pe:0 ua:0 ap:0 >> [root at clusty6.fra ~]# /etc/init.d/drbd stop >> Stopping all DRBD resourcesERROR: Module drbd is in use >> . >> [root at clusty6.fra ~]# cat /proc/drbd >> version: 0.7.22 (api:79/proto:74) >> SVN Revision: 2554 build by root at clusty6.fra, 2007-01-05 12:57:19 >> 0: cs:Unconfigured >> [root at clusty6.fra ~]# rmmod drbd >> ERROR: Module drbd is in use >> [root at clusty6.fra ~]# modprobe -r drbd >> FATAL: Module drbd is in use. >> [root at clusty6.fra ~]# lsmod >> Module Size Used by >> drbd 141396 1 >> ipv6 246304 12 >> autofs4 21764 1 >> hidp 16384 2 >> rfcomm 38040 0 >> l2cap 24064 10 hidp,rfcomm >> bluetooth 50276 5 hidp,rfcomm,l2cap >> bonding 79348 0 >> dm_mirror 29264 0 >> dm_mod 57624 1 dm_mirror >> video 17412 0 >> sbs 16576 0 >> i2c_ec 5760 1 sbs >> container 5120 0 >> button 7440 0 >> battery 10884 0 >> asus_acpi 17048 0 >> ac 5892 0 >> lp 13256 0 >> sg 34844 0 >> parport_pc 27684 1 >> serio_raw 7684 0 >> parport 37192 2 lp,parport_pc >> via686a 17160 0 >> hwmon 3972 1 via686a >> i2c_isa 5888 1 via686a >> tulip 50208 0 >> i2c_viapro 9108 0 >> pcspkr 3712 0 >> i2c_core 21888 4 i2c_ec,via686a,i2c_isa,i2c_viapro >> ext3 129800 2 >> jbd 58408 1 ext3 >> sym53c8xx 72088 3 >> scsi_transport_spi 24960 1 sym53c8xx >> sd_mod 20864 20 >> scsi_mod 134056 4 sg,sym53c8xx,scsi_transport_spi,sd_mod >> >> The drbd processes are terminated already: >> [root at clusty6.fra ~]# ps auxf >> USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND >> root 1 0.1 0.1 2008 668 ?
