Heinz, I thought I would forward this one to you just in case there is a bug on the delete. It is probably just my limited understanding of dmraid, but I thought after I deleted the partition in cfdisk and then deactivated the device (nvidia_ecaejfdi) node nvidia_ecaejfdip9 should disappear? It is still there. How do I get rid of it? This is on Archlinux. Here is a bit more info about my setup: [14:17 archangel:/home/david/archlinux/dmraid] # l /dev/mapper total 0 drwxr-xr-x 2 root root 0 2009-06-22 13:44 . drwxr-xr-x 23 root root 0 2009-06-22 13:44 .. crw-rw---- 1 root root 10, 60 2009-06-22 01:40 control brw------- 1 root disk 254, 0 2009-06-22 13:48 nvidia_ecaejfdi brw------- 1 root disk 254, 2 2009-06-22 01:40 nvidia_ecaejfdip5 brw------- 1 root disk 254, 3 2009-06-22 01:40 nvidia_ecaejfdip6 brw------- 1 root disk 254, 4 2009-06-22 01:40 nvidia_ecaejfdip7 brw------- 1 root disk 254, 5 2009-06-22 01:40 nvidia_ecaejfdip8 brw------- 1 root disk 254, 10 2009-06-22 13:44 nvidia_ecaejfdip9 (I have deleted this in cfdisk) ^^^^^^^^^^^^^^^^^^ brw------- 1 root disk 254, 1 2009-06-22 01:40 nvidia_fdaacfde brw------- 1 root disk 254, 6 2009-06-22 01:40 nvidia_fdaacfdep5 brw------- 1 root disk 254, 7 2009-06-22 01:40 nvidia_fdaacfdep6 brw------- 1 root disk 254, 8 2009-06-22 01:40 nvidia_fdaacfdep7 brw------- 1 root disk 254, 9 2009-06-22 01:40 nvidia_fdaacfdep8 [14:13 archangel:/home/david/archlinux/dmraid] # dmraid -rd -v -v NOTICE: /dev/sdd: asr discovering NOTICE: /dev/sdd: ddf1 discovering NOTICE: /dev/sdd: hpt37x discovering NOTICE: /dev/sdd: hpt45x discovering NOTICE: /dev/sdd: isw discovering NOTICE: /dev/sdd: jmicron discovering NOTICE: /dev/sdd: lsi discovering NOTICE: /dev/sdd: nvidia discovering NOTICE: /dev/sdd: nvidia metadata discovered NOTICE: /dev/sdd: pdc discovering NOTICE: /dev/sdd: sil discovering NOTICE: /dev/sdd: via discovering NOTICE: /dev/sdc: asr discovering NOTICE: /dev/sdc: ddf1 discovering NOTICE: /dev/sdc: hpt37x discovering NOTICE: /dev/sdc: hpt45x discovering NOTICE: /dev/sdc: isw discovering NOTICE: /dev/sdc: jmicron discovering NOTICE: /dev/sdc: lsi discovering NOTICE: /dev/sdc: nvidia discovering NOTICE: /dev/sdc: nvidia metadata discovered NOTICE: /dev/sdc: pdc discovering NOTICE: /dev/sdc: sil discovering NOTICE: /dev/sdc: via discovering NOTICE: /dev/sdb: asr discovering NOTICE: /dev/sdb: ddf1 discovering NOTICE: /dev/sdb: hpt37x discovering NOTICE: /dev/sdb: hpt45x discovering NOTICE: /dev/sdb: isw discovering NOTICE: /dev/sdb: jmicron discovering NOTICE: /dev/sdb: lsi discovering NOTICE: /dev/sdb: nvidia discovering NOTICE: /dev/sdb: nvidia metadata discovered NOTICE: /dev/sdb: pdc discovering NOTICE: /dev/sdb: sil discovering NOTICE: /dev/sdb: via discovering NOTICE: /dev/sda: asr discovering NOTICE: /dev/sda: ddf1 discovering NOTICE: /dev/sda: hpt37x discovering NOTICE: /dev/sda: hpt45x discovering NOTICE: /dev/sda: isw discovering NOTICE: /dev/sda: jmicron discovering NOTICE: /dev/sda: lsi discovering NOTICE: /dev/sda: nvidia discovering NOTICE: /dev/sda: nvidia metadata discovered NOTICE: /dev/sda: pdc discovering NOTICE: /dev/sda: sil discovering NOTICE: /dev/sda: via discovering INFO: RAID devices discovered: /dev/sdd: nvidia, "nvidia_ecaejfdi", mirror, ok, 1465149166 sectors, data@ 0 /dev/sdc: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0 /dev/sdb: nvidia, "nvidia_ecaejfdi", mirror, ok, 1465149166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0 [14:13 archangel:/home/david/archlinux/dmraid] # mc How do I remove the nvidia_ecaejfdip9 entry? -- David C.

I need to explain this a bit more:

<snip>

Now i cfdisk this device, are the nodes updated then? - I mean do i get the /dev/mapper/vidia_fffadgicp1 p2 p3 autimatically or do I need to run dmraid -ay for every partition i created? - Also what happens if partitions are deleted?
