Re: [zfs-discuss] Strange result when syncing between SPARC and x86
[b]Set up for test:[/b] (I picked v8 for no particular reason this linux install can speak zfs v3 and zpool v13, as can our solaris b101 installs, but some of the older solaris boxes we have can't I guess... so... I picked 8? I want to use this my little 500gb external ZFS disk. But first some testing!) sdd is an external USB drive. from dmesg: usb-storage: device found at 11 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete scsi 7:0:0:0: Direct-Access WDC WD50 00AAKB-00UKA0 PQ: 0 ANSI: 0 sd 7:0:0:0: [sdd] 976773168 512-byte hardware sectors (500108 MB) sd 7:0:0:0: [sdd] Write Protect is off sd 7:0:0:0: [sdd] Mode Sense: 33 00 00 00 sd 7:0:0:0: [sdd] Assuming drive cache: write through sd 7:0:0:0: [sdd] 976773168 512-byte hardware sectors (500108 MB) sd 7:0:0:0: [sdd] Write Protect is off sd 7:0:0:0: [sdd] Mode Sense: 33 00 00 00 sd 7:0:0:0: [sdd] Assuming drive cache: write through sdd: sdd1 sd 7:0:0:0: [sdd] Attached SCSI disk sd 7:0:0:0: Attached scsi generic sg4 type 0 ganymede:~# uname -a Linux ganymede 2.6.27.4-51.fc10.x86_64 #1 SMP Sun Oct 26 20:40:00 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux ganymede:~# zpool create -f external -o version=8 sdd ganymede:~# zpool status pool: external state: ONLINE status: The pool is formatted using an older on-disk format.

I downloaded and burnt b101 to dvd for x86 and solaris, i'm gonna install them tomorrow at work and try moving a pool between them to see what happens... Would be interesting to know how it'll work if move whole zpool not just sync with send/recv. But I think all will be fine there as is seems the problem is in send/recv part on the file system itself on different architectures.

Re: [zfs-discuss] Strange result when syncing between SPARC and x86
Hello Today I've suddenly noticed that symlinks (at least) are corrupted when sync ZFS from SPARC to x86 (zfs send | ssh | zfs recv). Example is: [EMAIL PROTECTED] ls -la /data/zones/testfs/root/etc/services lrwxrwxrwx 1 root root 15 Oct 13 14:35 /data/zones/testfs/root/etc/services - ./inet/services [EMAIL PROTECTED] ls -la /data/zones/testfs/root/etc/services lrwxrwxrwx 1 root root 15 Oct 13 14:35 /data/zones/testfs/root/etc/services - s/teni/.ervices Firstly I thought it's because original FS on SPARC is compressed... so I've just synced it locally on same machine and all was OK just different FS size since destination was not compressed. Then I've synced that copy again to x86 but result was same - symlinks were corrupted... so it's not compression. SPARC is snv_85 and x86 snv_82, I haven't got a chance yet to test on latest OpenSolaris. Any suggestions? Looks like the first 8 bytes aren't reversed.
