status update: the server is running under a slight load, some incoming mails and logging (messages, maillog). no data corruption so far. my assumption: since all writes go to /dev/sda3 via LVM, no writes go to the raid, therefore it doesn't sync, therefore no data corruption. cu RF> hi, RF> today I replaced two old 750GB disks in a RAID1 with two new 1TB RF> disks: RF> /dev/md0 (sda1, sdb1) (root filesystem) RF> /dev/md1 (sda3, sdb3) LVM with /var (and others) RF> - remove 750GB sdb, add new 1TB sdb, fdisk & sync sda -> sdb md0 and md1 RF> - remove 750GB sda, add new 1TB sda, fdisk & sync sdb -> sda md0 (md1 pending) RF> here I had some problems with grub, system did not boot from new sdb, RF> so I switched SATA ports on both disks and worked on grub & bios to RF> finally boot from sdb (maybe this was were the sh!t hit the fan) RF> on next boot, LVM reported the following: RF> Found duplicate PV efP9J0elVh1bokdArXcwsCB0KW0Yy9Ya: using /dev/sda3 not /dev/md1 RF> this doesn't look good, does it?
