Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

I''m troubleshooting an I/O performance problem with one of our applications that does a lot of writing, generally blocks just over 32K, sequentially writing large files. It''s a Solaris 10 x86 system with UFS disk. We''re often only seeing disk write throughput of around 6-8MB/s, even when there is minimal read activity. Running iosnoop shows that most of the physical

I encountered a strange libzfs behavior while testing a zone fix and want to make sure that I found a genuine bug. I''m creating zones whose zonepaths reside in ZFS datasets (i.e., the parent directories of the zones'' zonepaths are ZFS datasets). In this scenario, zoneadm(1M) attempts to create ZFS datasets for zonepaths. zoneadm(1M) has done this for a long time (since

Hello, I'm experiencing a kernel panic that appears to be caused by zfs. No errors are making it into /var/log/messages, but here is the error message that appears on my screen after panic (transcribed): panic solaris assert BSWAP_32(sa_hdr_phys->sa_magic) == SA_MAGIC, file: /src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/sa.c, line 1262 I can reproduce this by

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i''m trying to use the nfsv3 provider on S10U6, with the following simple script: #! /usr/sbin/dtrace -s #pragma D option quiet nfsv3:::op-read-start { printf("%s\n", args[1]->noi_curpath); } however, when running it, i get the following error: dtrace: failed to compile script ./nfs2.d: line 5: failed to grab

I am teaching a DTrace class and a student noticed that 2 iosnoop scripts run in two different windows were producing different results. I was not able to answer why this is. Can anyone explain this. Here are the reults from the two windows: # io.d ... sched 0 <none> 1024 dad1 W 0.156 bash 1998

I contacted the author of ''lsof'' regarding the missing ZFS support. The command works but fails to display any files that are opened by the process in a ZFS filesystem. He indicates that the required ZFS kernel structure definitions (header files) are not shipped with the OS. He further indicated that he rummaged through the OpenSolaris source tree and the files doesn''t

Hi. I''ve almost all file system functions working. I started to run some heavy file system regression tests. They work. fsx wasn''t able to break my port, but the test you can find here: http://people.freebsd.org/~kan/fsstress.tar.gz broke it.

Hello, I've installed & configured NUT 2.0.4 connected over a serial port to an MGE USBS 750. When the UPS enters the 'critical' state (ie, battery load below the defined battery.charge.low AND power input off), the UPS just shutdown itself instead of notifying NUT. When I say the UPS just shutdown, I mean it autonomously shut down itself within one second after reaching the

The time has come to review the current Contributor and Core contributor grants for ZFS. Since all of the ZFS core contributors grants are set to expire on 02-24-2009 we need to renew the members that are still contributing at core contributor levels. We should also add some new members to both Contributor and Core contributor levels. First the current list of Core contributors: Bill

I''ve noticed that the dsl_dataset_t that points to a given dataset changes during the life time of a ''zfs create'' command. We start out with one dsl_dataset_t* during dmu_objset_create_sync() but by the time we are later mounting the dataset we have a different in memory dsl_dataset_t* referring to the same dataset. This causes me a big issue with per dataset

Hello all... We are getting this error: "E2BIG - Arg list too long", when trying to send incremental backups (b89 -> b101). Do you know about any bugs related to that? I did a look on the archives, and google but could not find anything. What i did find was something related with wrong timestamps (32bits), and some ZFS test on the code: zfs_vnops.c. But the error is EOVERFLOW...

Dear Rgurus, To my knowledge the best way to visualize the distribution of a discrete variable X is plot(table(X)) The problem which I have is the following. I have to discrete variables X and Y which distribution I would like to compare. To overlay the distribution of Y with lines(table(Y)) gives not satisfying results. This is the same in case of using density or histogram. Hence, I am
