Re: [zfs-discuss] space_map again nuked!!
Did you see this thread? http://opensolaris.org/jive/thread.jspa?messageID=500659#500659 He had problems with ZFS. It turned out to be faulty RAM. ZFS is so sensitive it detects and reports problems to you. No other filesystem does that, so you think ZFS is problematic and switch. But the other filesystems is slowly corrupting your data, because they dont notice problems. In other words, I suspect the problem is not in ZFS, but somewhere else. Maybe hardware? Maybe BIOS? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Did you see this thread? http://opensolaris.org/jive/thread.jspa?messageID=5006 59#500659 I get on this link: Tomcat http error 500: The server encountered an internal error () that prevented it from fulfilling this request.

That could be possible because its very cheap hardware from the hosting service Hetzner. I will run a memtest to get more information about it. If I detect errors on the ram and they will exchange it, how can I repair my defective spacemap? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

As far as I understand it have been working for you for some time. How long was that? Have you been doing something new and different with your system lately? I will run a memtest to get more information about it. If I detect errors on the ram and they will exchange it, how can I repair my defective spacemap? Here the same trick with aok/zfs_recover may work, but in general the only supported way at the moment is to backup all data, destroy and recreate pool and then restore data back.

My server no more reboots because the ZFS spacemap is again corrupt. I just replaced the whole spacemap by recreating a new zpool from scratch and copying back the data with zfs send zfs receive. Did it copied corrupt spacemap?! Definitely no. It suggests that you may have and issue with hardware, for example with memory, or CPU and/or cache, or some other components. regards Victor ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] space_map again nuked!!
I'm really angry against ZFS: My server no more reboots because the ZFS spacemap is again corrupt. I just replaced the whole spacemap by recreating a new zpool from scratch and copying back the data with zfs send zfs receive. Did it copied corrupt spacemap?! For me its now terminated. I loss to much time and money with this experimental filesystem. My version is Zpool ZFS of snv_111b. I will switch back to Linux to ext4. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
