Thanks, I will update with my results of your attachment.

I've had no success with fuse on Nexenta, but I can continue to research the
OpenSolaris fuse builds and update as I find anything worthwhile.

Hi!

We checked more carefully this situation. Using not thread-safe "readdir"
function everything went smoothly (instead of "readdir_r"). 

The structure keeping entries in directories looks on Nexenta like this:

typedef struct dirent {

        ino_t           d_ino;          /* "inode number" of entry */

        off_t           d_off;          /* offset of disk directory entry */

        unsigned short  d_reclen;       /* length of this record */

        char            d_name[1];      /* name of file */

} dirent_t;

We can read from this that there is just one byte reserved for the file name
whereas in other operating systems it is typically 256 bytes.

We made appropriate changes to our code so that it is now compatible with
Nexenta. Please find the modified file in the attachement. 

(And we wait for the tips on how to install fusefs on Nexenta if you managed
to install it)

Kind regards

Michal

Thanks for the info, looks like I had to submit a bug after all: 

Details:

PROBLEM: When the mfschunkserver has chunks and a restart occurs,
mfschunkserver will segfault
REPRODUCE:
OS: SunOS nexgfs 5.11 NexentaOS_134f i86pc i386 i86pc Solaris
COMPILE: Add -D_POSIX_PTHREAD_SEMANTICS to mfschunkserver/MakeFile CFLAGS
variable.
RUN: Start the mfschunkserver and allow a few chunks to copy. Stop the
process, and restart.
OUTPUT:

(gdb) run -d

Hi Robert!

We'll give it a closer look, for the moment you can try to add in Makefile
compilator option:

"-D_POSIX_PTHREAD_SEMANTICS"

It helps in Solaris 10, and should help in Nexenta too.

Kind regards

Subject: [Moosefs-users] Compile on Nexenta Fails

Hello,

When compiling moosefs on NexentaStor 3.0.4(Community), I use the following
configure options:

./configure --disable-mfsmaster --disable-mfscgi --disable-mfscgiserv
--disable-mfsmount

After configuring, make returns the following output:
