I'm having problems with reads and writes to my LVM disks stalling after transferring a bit of data. I have 2 250G SATA disks in a logical volume. I initially only had one of the drives in the LV with JFS, the other was stand alone with XFS. I was able to transfer all of the data (~90% full) off the standalone drive onto the LV, and then I changed the partition to Linux LVM, and extended my LG/LV to include both drives. I remounted,resized the JFS partition, and confirmed the additional space with df. But now I see problems reading/writing data. If I try to transfer a 1Gig file from root (PATA disk with ext3) to my LV it copies the 1st ~400M at nice fast transfer speed, but then it seems to stall out, and xfer rate drops to ~1M/s! I see the same behavior if I try to copy a file from LVM to my root, except it gets about 600M before stalling. Any ideas what is going on here?? I've tried moving the disks to a different computer (using a sata_piix controller vs sata_sil). So I don't think it is the SATA controller, and like I said the drives worked fine independently. So I think probably has something to do with LVM, but I'm not sure how to go about debugging this problem (I don't see any errors in the logs). BTW, this is a x86 box running fedora core 4 (2.6.13-1.1526_FC4 kernel) LVM version: 2.01.08 (2005-03-22) Library version: 1.01.02 (2005-05-17) Driver version: 4.4.0 Thanks, Patrick _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
