Re: [developer] ZFS - RAIDZ1 Recovery (Evgeny)

Hi all, The broken disk is being currently cloned using recoverdisk utility. It takes long, because it has a lot of bad sectors, but it seems like it passed most of them already. I will notify the post, when it is finished. Thank you, Evgeny. On Jun 5, 2016 9:04 AM, "Arne Jansen" wrote: > On 05

Re: [developer] ZFS - RAIDZ1 Recovery (Evgeny)

Unfortunately tools like photorec won't work (I assume the tool scans the disk and looks for some JPEG headers, etc.) as this was RAIDZ1 pool, so none of the disks contains recognizable data. Two questions come to my mind: 1. Is it possible to recover the data now? 2. Is it possible to recover the

Re: [developer] ZFS - RAIDZ1 Recovery (Evgeny)

Hello Evgeny, without trying to understand what exactly you've done to the pool: If you think that in theory that data should still be there you can try to use tools like photorec. There's a chance it can recover most of your data, but probably without filenames. Tons of work awaiting you there..
