https://bugzilla.suse.com/show_bug.cgi?id=1131931 https://bugzilla.suse.com/show_bug.cgi?id=1131931#c2 --- Comment #2 from heming zhao --- ocfs2-tools related code: do_file_defrag + struct ocfs2_move_extents me = { | .me_start = 0, | .me_len = buf->st_size, | .me_flags = OCFS2_MOVE_EXT_FL_AUTO_DEFRAG | }; | + fd = open64(file, O_RDWR, 0400); | + ioctl(fd, OCFS2_IOC_MOVE_EXT, &me) //return errno: ENOSPC //errno ENOSPC response with "No space left on device". kernel related code: ocfs2_defrag_extent() { ... ... ret = __ocfs2_claim_clusters(handle, context->data_ac, 1, *len, &new_phys_cpos, &new_len) ... ... if (new_len != *len) { if (!partial) { context->range->me_flags &= ~OCFS2_MOVE_EXT_FL_COMPLETE; ret = -ENOSPC; need_free = 1; goto out_commit; } } ... ... } ------------ This bug has a workround (without remount). when defragfs reports -ENNOSPC, use dd to create some new files to consume la-window. After ocfs2 switch to another la-window, re-run defrag may succeed. ``` tw-xfs1:~ # defragfs.ocfs2 /mnt/test_from_dd1 defragfs.ocfs2 1.8.7 [ERROR]Move extent failed:"/mnt/test_from_dd1" - No space left on device [ERROR]"/mnt/test_from_dd1":No space left on device tw-xfs1:~ # tw-xfs1:~ # dd if=/dev/zero of=/mnt/zhm.1 bs=4k count=200 200+0 records in 200+0 records out 819200 bytes (819 kB, 800 KiB) copied, 0.0166738 s, 49.1 MB/s tw-xfs1:~ # dd if=/dev/zero of=/mnt/zhm.2 bs=1M count=20 20+0 records in 20+0 records out 20971520 bytes (21 MB, 20 MiB) copied, 0.118353 s, 177 MB/s tw-xfs1:~ # defragfs.ocfs2 /mnt/test_from_dd1 defragfs.ocfs2 1.8.7 /mnt/test_from_dd1: Succeeded ``` -- You are receiving this mail because: You are on the CC list for the bug.
