Hi all, During our test on kernel 2.6.32, we found a problem about SCSI device hot-plug and this may be a bug. Our SCSI host is MPT2SAS. assume the SCSI disk is /dev/sdb and it's SCSI ID is 0:0:1:0. First, Let's mount it at /mnt/test with following command: mount /dev/sdb /mnt/test now we can access this disk through /mnt/test Then we hot plug out this device as following: echo 1 > /sys/block/sdb/device/delete At here, /mnt/test is not accessible but /dev/sdb is still there. Then we re-scan the host: echo "0 1 0" > /sys/class/scsi_host/host0/scan We found that a new dev node such as sdf is allocated to this disk but sdb is not freed and is not reusable. We want that sdb can be freed when we hot plug-out the disk and can be reused when we plug-in a new disk. Is this some kind of bug? Has it been fixed in the newer version? Any suggestion or any workaround?
