I had hoped there was a way to skip that. Tried without it -- only difference in the logs was seeing that it picked up the full size of the partition. So, same result. > Also might be useful to know make/model of ssd, plus motherboard make/model > (in case commenting out size does not fix)! It's an Intel X25-E, 64GB. It's a place-holder until some bigger ones we have on order show up. The mother board is a SuperMicro X8DT6. SSDs are connected to onboard SATA ports, data drives are connected to LSI 9211-8i (SAS2008) Maybe there is a special way I need to do the partition? My goal was to throw 6 journals on this disk, and it is partitioned like so: Model: ATA SSDSA2SH064G1GC (scsi) Disk /dev/sda: 64.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 512MB 511MB primary raid 2 512MB 2511MB 2000MB primary raid 3 2511MB 6512MB 4000MB primary raid 4 6512MB 64.0GB 57.5GB extended 5 6513MB 15.1GB 8590MB logical 6 15.1GB 23.7GB 8590MB logical 7 23.7GB 32.3GB 8590MB logical 8 32.3GB 40.9GB 8590MB logical 9 40.9GB 49.5GB 8590MB logical 10 49.5GB 58.1GB 8590MB logical So, sda5-10 are my journal partitions. I know that I have consumed most of the drive here, and that is bad for the SSD and such, but it really is a temporary setup. - Travis On Thu, Nov 8, 2012 at 3:24 AM, Mark Kirkwood <mark.kirkwood@xxxxxxxxxxxxxxx> wrote: > On 08/11/12 21:08, Wido den Hollander wrote: >> >> >> >> On 08-11-12 08:29, Travis Rhoden wrote: >>> >>> Hey folks, >>> >>> I'm trying to set up a brand new Ceph cluster, based on v0.53.
