Hello, Thanks, I also checked that post earlier today. Basically, it looks like MDADM array, and LVM on top (and possibly FS inside the VMs) need to be created with manual calculations for alignment and these calculations need to be specified on the command line at the time of creation. It is pity to find out this now, when server is in active use - many manuals mention that MDADM, LVM, etc are smart enough these days to make these calculations automatically at the time of creation, but this does not appear to be true and that's where problems come from later on. I guess my only way to fix this is to migrate everything off that server and reinstall it from scratch, throwing away things like MDADM and LVM this time and replacing them with ZFS for storage purposes. Thanks all. _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
