Ok, we have a couple of options What I have done so far is to hex edit your GPT headers, though technically they are valid. Sector 2 is the GPT header and normally the header length is recorded as 92 bytes. Yours claim that the header it 512 bytes or the entire sector. The crc32 value is calculated based on byte 0 - header size. Our GPT code is performing the crc comparison based on the 92 valid bytes in the header along with 512 - 92 bytes of random memory, so the header crc fails and GEOM refuses the header. We need to fix the GPT code to handle this correctly, so you can give me a little time to fix it correctly, or we can just fix your existing GPT headers to work with our code... Before: GEOM: md6: corrupt or invalid GPT detected. GEOM: md6: GPT rejected -- may not be recoverable. After: GEOM: md6: the secondary GPT table is corrupt or invalid. GEOM: md6: using the primary only -- recovery suggested. =>34 1953525101 md6 GPT (466T) 34 222 - free - (111K) 256 19535084951 !6a898cc3-1dd2-11b2-99a6-080020736631 (932G) 1953508751 163849 !6a945a3b-1dd2-11b2-99a6-080020736631 (8.0M) Hopefully I don't need to tell you proceed with caution here, but if you want to rewrite the headers, I've attached 6 files which contain the modified primary and secondary headers. The seek values below for the secondary header are calculated for your drive.

Re: i am desperate over some GPT tables
thanks for replying - my problem just got worse. i used to be able to import and see the pools by typing zpool import and then the specific name of the pool, in this case 'lakez' that used to work and i used to be able to see the solaris pool (although it gave me the error GPT table corrupt which i mentioned in last post) now though, i cant see any pools, after loading back into solaris and exporting again just to make sure the same thing happens a 'zpool import -f lakez' results in no pools under zpool status.. ive done nothing different in terms of commands and machine is the same... im a musician and i just use zfs to keep all my samples on so bear with me if i dont understand im not a proper geek yet but i want to be when i grow up... ad0: 238475MB at ata0-master UDMA100 acd0: DVDR at ata0-slave UDMA33 ad4: 953869MB at ata2-master SATA300 ad6: 953869MB at ata3-master SATA300 ad8: 953869MB at ata4-master SATA300 SMP: AP CPU #1 Launched!

Re: i am desperate over some GPT tables
been looking for months now, trawled google no help, i just dont understand. do you need a GPT table with zfs ? i have a pentium D 3ghz (running 64bit stable 7.2) and i cant seem to import my zpool into it exported fine on solaris , its definitely the same version (v13) but when i import into zfs it says GPT tables corrupt ? why ? and what does this mean ? please help me. please. -- )) (( c[_] ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
