I just rcvd a brand new 10TB Ironwolf Red drive; not the first I have set up by a long shot, but there seems to be an issue in getting this one formatted.
No matter what I do I end up with messages about misaligned partitions. I tried the 16.04 ubuntu server install first as it required an extra partition set up that I didn't really want, but it complained if one was not there for grub. I tried various combinations in the installer and then gave up on it and tried to finish it manually. I can get acceptable partitions from parted this way: parted -a optimal /dev/sdb (parted) unit s (parted) mkpart primary linux-swap 1114095 39058859 But mkswap complains: mkswap /dev/sdb3 mkswap: warning: /dev/sdb3 is misaligned Setting up swapspace version 1, size = 18.1 GiB (19427713024 bytes) no label, UUID=33b9ea94-c7ea-4db1-b3df-dbaf88595b4d I also have a similar issue with mkfs.ext4. I've checked out various suggestions such as https://rainbow.chard.org/2013/01/30/how-to-align-partitions-for-best-performance-using-parted/ # cat /sys/block/sde/queue/optimal_io_size 33553920 # cat /sys/block/sde/queue/minimum_io_size 4096 # cat /sys/block/sde/alignment_offset 0 # cat /sys/block/sde/queue/physical_block_size 4096 "Add optimal_io_size to alignment_offset and divide the result by physical_block_size" This gives a non-integer result which I presume the author intended should be rounded to integer: (33553920 + 0) / 4096 = 8191.87 => 8192 I have been trying various combinations of Ubuntu systems and work arounds for the last 12 hours and I am no closer to making everything happy than I was when I started. I've also fiddled with cfdisk and gdisk. Is anyone else having this problem? My goal with the install is to: 1) Not activate UEFI 2) have an 80 MB /, a swap and the remainder of the 10TB in /lib0. 3) Have Ubuntu install, gpt, mkswap and mkfs.ext4 all happy. -- +---------------------------------------------------------------+ | Dale Amon Immortal Data | | CEO Midland International Air and Space Port | | a...@vnl.com "Data Systems for Deep Space and Time" | +---------------------------------------------------------------+ -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
