Hi, I've got two machines connecting to an ocfs2 filesystem on an iSCSI target provided by our hosting company (the iSCSI target is on an HP SAN). After a bit of usage any deleted files disappear, but checking the usage with "df" shows that space is not being reclaimed. I've unmounted the partition from both nodes and run "fsck.ocfs2 -fy /dev/sdb1" which found a whole lot of orphaned inodes which is apparently fixed. Remounting showed that the space still was not reclaimed. I did some testing to see whether the information supplied by "df" was simply incorrect, but once the partition showed as full I could not write anything more to it. After the weekend I tried to remount the full partition and had the attached kernel errors splash across the screen. I had to power cycle the server through the hosting company's interface to get it responsive again. I then had to do a mkfs.ocfs2 to be able to mount the partition without those kernel errors. OS: Ubuntu 9.04 (Jaunty) ocfs2: 1.5.0 (from "modinfo ocfs2") ocfs2-tools: 1.3.9-0ubuntu3 Is there any more information I can provide that might help with this? Thanks Guy -- Don't just do something...sit there! -------------- next part -------------- stoat kernel: [ 244.947060] general protection fault: 0000 [#1] SMP stoat kernel: [ 244.947060] general protection fault: 0000 [#1] SMP stoat kernel: [ 244.947180] last sysfs file: /sys/fs/o2cb/interface_revision stoat kernel: [ 244.947180] last sysfs file: /sys/fs/o2cb/interface_revision stoat kernel: [ 244.949863] Stack: stoat kernel: [ 244.949863] Stack: stoat kernel: [ 244.950065] ffff88007185bc50 ffff88007f20c690 ffff88007185bc30 ffffffff802b3081 stoat kernel: [ 244.950065] ffff88007185bc50 ffff88007f20c690 ffff88007185bc30 ffffffff802b3081 stoat kernel: [ 244.950291] ffff88007185bcb0 ffffffff802b31e3 ffff88007185bc68 00000010802b3081 stoat kernel: [ 244.950291] ffff88007185bcb0 ffffffff802b31e3 ffff88007185bc68 00000010802b3081 stoat kernel: [ 244.950562] Call Trace: stoat kernel: [ 244.950562] Call Trace: stoat kernel: [ 244.950614] [<ffffffff802b3081>] mempool_alloc_slab+0x11/0x20 stoat kernel: [ 244.950614] [<ffffffff802b3081>] mempool_alloc_slab+0x11/0x20 stoat kernel: [ 244.950704] [<ffffffff802b31e3>] mempool_alloc+0x53/0x130 stoat kernel: [ 244.950704] [<ffffffff802b31e3>] mempool_alloc+0x53/0x130 stoat kernel: [ 244.950792] [<ffffffff802b31e3>] ?

How (in heartbeat) can I specify only one node at any one time can mount OCFS2, in a active / passive 2 node configuration? -----Original Message----- From: ocfs2-users-bounces at oss.oracle.com [mailto:ocfs2-users-bounces at oss.oracle.com] On Behalf Of Guy Sent: Tuesday, October 27, 2009 10:48 AM To: ocfs2-users at oss.oracle.com Subject: [Ocfs2-users] Space not reclaimed after deletion of files. Hi, I've got two machines connecting to an ocfs2 filesystem on an iSCSI target provided by our hosting company (the iSCSI target is on an HP SAN). After a bit of usage any deleted files disappear, but checking the usage with "df" shows that space is not being reclaimed. I've unmounted the partition from both nodes and run "fsck.ocfs2 -fy /dev/sdb1" which found a whole lot of orphaned inodes which is apparently fixed. Remounting showed that the space still was not reclaimed. I did some testing to see whether the information supplied by "df" was simply incorrect, but once the partition showed as full I could not write anything more to it. After the weekend I tried to remount the full partition and had the attached kernel errors splash across the screen. I had to power cycle the server through the hosting company's interface to get it responsive again. I then had to do a mkfs.ocfs2 to be able to mount the partition without those kernel errors. OS: Ubuntu 9.04 (Jaunty) ocfs2: 1.5.0 (from "modinfo ocfs2") ocfs2-tools: 1.3.9-0ubuntu3 Is there any more information I can provide that might help with this?
