Hi, I don't know really which subsystem this, so I'm sending this to the linux-kernel list. Please direct me to a more appropriate place if this is not correct. I'm using a 3ware 9500 with Linux 2.6.18.1. I've grown the HW raid5-array and here is where the problem begins. After the card had expanded the array, I used "blockdev --rereadpt /dev/sdk" to get the kernel to recognize the now larger device. The last step was to do a "pvresize /dev/sdk". The problem is that pvresize still thought that the device was at the original size. From the lvm mailinglist I found out that pvresize used the same mechanism as "blockdev --getsz" to get the size of the disks, so I tested this and found that blockdev also reported the device to have the wrong size. So, if I do: # cat /sys/block/sdk/size 4882708480 and # blockdev --getsz /dev/sdk 3906166784 Apparently /sys/block/sdk/size is updated with the new size, but whatever "blockdev --getsz" and "pvresize" is querying is not. If I reboot, everything works correctly. Best Regards, /LM Ps. please keep me as Cc: on this; since I'm not subscibed to the linux-kernel list.. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
