Hi Vincenzo, theoretically you might also be able to use a directory. But dont forget, that ceph relies on this xattr stuff from the FS. XFS is currently the most save choice to choose. Also you will need a journal. This is usually a symblink to a device inside the osd directory. My advice to you is, that you should first, regulary, create a regular device/disk for osd and see how this looks like. Also, you should consider, that udev is used for ceph disk activation. So you would have to modify this udev rules aswell. All in all its a lot of hacking you need to do. Unless you have a really serious reason to do so, i wont do it. In case of upgrades, this whole will also clash without end. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 03.05.2016 um 22:00 schrieb Vincenzo Pii: > ceph-disk can prepare a disk a partition or a directory to be used as a > device. > > What are the implications and limits of using a directory? > Can it be used both for journal and storage? > What file system should the directory exist on? > > > Vincenzo Pii | TERALYTICS > *DevOps Engineer > * > > Teralytics AG | Zollstrasse 62 | 8005 Zurich | Switzerland > phone: +41 (0) 79 191 11 08 > email: vincenzo.pii@xxxxxxxxxxxxxx > <mailto:first-name.last-name@xxxxxxxxxxxxxx> > www.teralytics.net > <http://www.google.com/url?q=http%3A%2F%2Fwww.teralytics.net%2F&sa=D&sntz=1&usg=AFrqEzen-TJ7SdCY0QomEByjPQDNuEuP0A> > > Company registration number: CH-020.3.037.709-7 | Trade register Canton > Zurich > Board of directors: Georg Polzer, Luciano Franceschina, Mark Schmitz, > Yann de Vries > > This e-mail message contains confidential information which is for the > sole attention and use of the intended recipient.
