Re: [zfs-discuss] Help! OS drive lost, can I recover data?
If your data-disks are OK, then do not worry. Just reinstall your OS and import the data-pool. Thanks. 2012/8/28 Adam adamthek...@gmail.com Hi All, Bit of a newbie here, in desperate need of help. I had a fileserver based on FreeNAS/ZFS - 4 SATA drives in RaidZ, with the OS on a USB stick (actually, a spare MicroSD card in a USB adapter). Yesterday we had a power outage - that seems to have fried the MicroSD card. The other disks *appear* to be OK (although I've done nothing much to check them yet - they're being recognised on boot), but the OS is gone - the MicroSD is completely unreadable. I think I was using FreeNAS 0.7 - I honestly can't remember. Can I recover the data? Can anyone talk me through the process? Thanks - Adam... ** ** ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

What are you calling the root zfs on the destination? You're not trying to overwrite / are you? That would ... admittedly ... not be so straightforward. But I don't think it's impossible.

Hi All! Can i create pool or dataset with name that contains non-latin letters (russian letters, specific germany letters, etc ...)? I tried to create pool with non-latin letters, but could not. In ZFS User Guide i see next information: Each ZFS component must be named according to the following rules: - Empty components are not allowed. - Each component can only contain alphanumeric characters in addition to the following four special characters: - Underscore (_) - Hyphen (-) - Colon (:) - Period (.) - Pool names must begin with a letter, except for the following restrictions: - The beginning sequence c[0-9] is not allowed - The name log is reserved - A name that begins with mirror, raidz, or spare is not allowed because these name are reserved. In addition, pool names must not contain a percent sign (%) - Dataset names must begin with an alphanumeric character. Dataset names must not contain a percent sign (%). As you can see guide has no information about only-latin letters. Thanks. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
