Re: not finding extra partitions
removed the cable from one drive and rebooted for a test. All seemed to go well, system ran in degraded mode. When I reconnected drive, only 1 of the 3 partitions on the drive are recognized. 2 of my 3 /dev/md- arrays still run in degraded mode. How can I force a "good" partition so the array will rebuild? raidhotadd /dev/mdX /dev/sd?? then it reconstructs. -sv
Re: not finding extra partitions
Thanks Seth! I dug through the linux-raid archives last night and found the answer too. Got everything resynced last night. I am using RH 6.1 2.2.12-20 with a Promise EIDE-MaxII with 3 Maxtor 51536U3 ide drives; 2 of these drives on Promise card, and 3rd on secondary of motherboard. All seems to be working well. Total cost: 150*3 + 26 = 476 dollars for 30Gig of RAID5. /dev/md0 - /dev/hdc1 /dev/hde1 /dev/hdg1 mounted as /usr /dev/md1 - /dev/hdc5 /dev/hde5 /dev/hdg5 mounted as /home /dev/md2 - /dev/hdc6 /dev/hde6 /dev/hdg6 mounted as /usr1 I have a SOHO and am using the RAID5 as a "network appliance". /usr1/xtools exported as nfs and SAMBA - contains Solaris and win32 cross development tools. /usr1/rtosdev exported as nfs and SAMBA - contains development code /home exported as nfs and SAMBA - misc and NIS home directory Has anyone seen any problems in long term use of linux RAID5 in this or any other environment?

not finding extra partitions
I had my raid5 up and running with 3 15g ide disks. I shutdown and removed the cable from one drive and rebooted for a test. All seemed to go well, system ran in degraded mode. When I reconnected drive, only 1 of the 3 partitions on the drive are recognized. 2 of my 3 /dev/md- arrays still run in degraded mode. How can I force a "good" partition so the array will rebuild? -- --- +-+ | Douglas EganWind River | | Sr. Staff Engineer | | Tel : 847-837-1530| | Fax : 847-949-1368| | HTTP : http://www.windriver.com| | Email : [EMAIL PROTECTED] | +-+
