Re: [zfs-discuss] help with a BIG problem, can't import my zpool anymore

Then wait and see if it finishes and if it still freezes the box. -- Best regards, Robert Milkowskimailto:[EMAIL PROTECTED] http://milek.blogspot.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] help with a BIG problem, can't import my zpool anymore
I got more info. I can run zpool history and this is what I get: 2008-05-23.00:29:40 zfs destroy tera/[EMAIL PROTECTED] 2008-05-23.00:29:47 [internal destroy_begin_sync txg:3890809] dataset = 152 2008-05-23.01:28:38 [internal destroy_begin_sync txg:3891101] dataset = 152 2008-05-23.07:01:36 zpool import -f tera 2008-05-23.07:01:40 [internal destroy_begin_sync txg:3891106] dataset = 152 2008-05-23.10:52:56 zpool import -f tera 2008-05-23.10:52:58 [internal destroy_begin_sync txg:3891112] dataset = 152 2008-05-23.12:17:49 [internal destroy_begin_sync txg:3891114] dataset = 152 2008-05-23.12:27:48 zpool import -f tera 2008-05-23.12:27:50 [internal destroy_begin_sync txg:3891120] dataset = 152 2008-05-23.13:03:07 [internal destroy_begin_sync txg:3891122] dataset = 152 2008-05-23.13:56:52 zpool import -f tera 2008-05-23.13:56:54 [internal destroy_begin_sync txg:3891128] dataset = 152 apparently, it starts destroying dataset #152, which is the parent snapshot of the clone I issued the command to destroy. Not sure how it works, but I ordered the deletion of the CLONE, not the snapshot (which I was going to destroy anyway). The question is still, why does it hang the machine? Why can't I access the filesystems? Isn't it supposed to import the zpool, mount the ZFSs and then do the destroy, in background?

Re: [zfs-discuss] help with a BIG problem, can't import my zpool anymore
I let it run for about 4 hours. when I returned, still the same: I can ping the machine but I can't SSH to it, or use the console. Please, I need urgent help with this issue!

2008/5/24 Hernan Freschi [EMAIL PROTECTED]: I let it run while watching TOP, and this is what I got just before it hung. Look at free mem. Is this memory allocated to the kernel? can I allow the kernel to swap? No, the kernel will not use swap for this. But most of the memory used by the kernel is probably in caches that should release memory when needed. Is this a 32 or 64 bit system? ZFS will sometimes use all kernel address space on a 32-bit system. You can give the kernel more address space with this command (only on 32-bit system): eeprom kernelbase=0x5000 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
