From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christina Braun Date: Tue, 24 Jul 2007 15:13:06 +0000 Subject: big count of sda-partitions Message-Id: <46A61702.7040702@mail.informatik.uni-essen.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org Hello, I have the bad and stressig problem to use a lot of partitions (>16) on our hardwareraid,3ware 9590SE-16ML, >2 TB, debian-etch, 2.6.18-4-amd64. I have compiled parted, use the gpt-Partitiontable (theoretical for >2TB and 128 Partitions) . I have tested with 14 partitions with no problems. I use udev, like it, and have succesfull name the disks with it. (2 internal, 1 hw-raid). The kernel-config of this debian-etch has CONFIG_PARTITION_ADVANCED=y, CONFIG_EFI_PARTITION=y, By creating the partitions for the final production-system with parted, no errors first, with more partitions, which I can create in parted without errors (but not delete!), I can only see sda1-15Partition under /dev. Also reboot makes no chances. I see the parameter /sys/block/sda/range = 16. Changes this by echo (example:echo 21 >/sys/block/sda/range) are not approved. Is that the tuning-parameter? How can I increase the number of partitions for udev? Or is this the total wrong place? I have searched in the web and kernel-sources, but nobody seems to have the same problem or interest for using a lot of partitions under linux. ThankYou very much, with best regards, Christina -- ********************************************** /\_/\ * email: braun@dc.uni-due.de / 0 0 \ * Christina Braun ==v== * FB. 5, ICB / Informatik \ W / * University DE | | * Schuetzenbahn 70 tel.: + 49 201 183-3929 / ___ \ / * D-45127 Essen fax.: + 49 201 183-2419 / / \ \ | **********************************************(((-----)))-' ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
