Saya telah menemukan masalah aneh ... jika saya memiliki file gambar disk (DMG) yang berada pada bagian NFS yang hanya dapat dibaca, saya tidak dapat membukanya di Mac OS X 10.7.5. File yang sama terbuka dengan baik ketika diakses melalui AFP. Namun, mencoba membukanya menggunakan hdiutil attach
ketika mereka berada di NFS berbagi hasil dalam "lampiran gagal - sistem file Read-only":
bash-3.2# /usr/bin/hdiutil attach /Volumes/nfs_share/Some.dmg
hdiutil: attach failed - Read-only file system
Bahkan jika bagian AFP hanya baca, saya dapat melampirkan gambar yang sama. Tetapi untuk beberapa alasan, berbagi NFS read-only tidak berfungsi.
Pada akhirnya apa yang ingin saya lakukan adalah melampirkan gambar dengan file bayangan , untuk me-mount gambar read-only sebagai read-write. Tetapi ini juga gagal dengan cara yang sama:
bash-3.2# /usr/bin/hdiutil attach /Volumes/nfs_share/Some.dmg -mountpoint /Somewhere -shadow /path/to/Some-Shadow
hdiutil: attach failed - Read-only file system
Sekali lagi, ini berfungsi dengan baik jika gambar disajikan melalui AFP. Ini juga berfungsi dengan baik jika berbagi NFS adalah baca-tulis, tetapi untuk alasan keamanan saya tidak bisa melakukan itu.
Bagaimana saya bisa me-mount file DMG yang berada di bagian NFS read-only?

fs_usage
untuk melihat apakah saya dapat menangkap filesystem yang membuat panggilan tulis - mungkin mengajukan bug dengan Apple. Tampaknya Anda harus dapat membaca DMG hanya baca - tetapi mungkin ada beberapa alasan teknis yang lebih dalam mengapa gagal dan OS memerlukan pesan kesalahan yang lebih baik untuk memberi tahu kami mengapa ...hdiutil
dengan-debug
saklar, saya dapat memposting log-log itu di sinirpcinfo -p
di server? Apa output darimount
pada Mac Anda? Bisakah Anda juga menambahkan baris yang relevan/etc/exports
di server NFS ke pertanyaan?hdiutil -debug
dan informasi yang saya minta untuk pertanyaan Anda?Jawaban:
Saya sudah tertarik dengan pertanyaan ini sejak November 2012 dan bahkan membuat FreeNAS VM untuk mereproduksi masalah ini.
Saya akhirnya menyerah tetapi karena pertanyaan telah diresusitasi saya akan membagikan apa yang saya temukan saat itu dan di jam-jam terakhir (untungnya saya tidak menghapus VM) dan apa yang saya pikir penyebab masalah ini adalah. Saya juga menemukan solusi.
Pengaturan saya
Pertama-tama, ini adalah setup pengujian saya:
OS X 10.8.2 (maaf, tidak ada 10.7.5 di sekitar).
FreeNAS (FreeBSD 8.2-RELEASE-p1)
(Versi OP adalah FreeBSD 8.2-RELEASE-p7 - Saya tidak dapat menemukan versi yang sama.)
Sebuah NAS filesystem di
/mnt/raid
:Seorang pengguna bernama
netboot
:Sistem file AFP (
/mnt/raid/netboot
) diekspor sebagainetboot
:(Perhatikan bahwa ini dikonfigurasi hanya baca).
Sistem file NFS (jalur yang sama dengan sistem file AFP, agar sesuai dengan konfigurasi OP:)
/mnt/raid/netboot
:AFP bekerja, NFS tidak
Saya memasang sistem file read-only AFP sebagai pengguna
netboot
menggunakan Finder dengan ⌘K:dan memasang file gambar DMG tanpa masalah:
Kemudian saya unmount dan ⌘Kme-mount filesystem NFS read-only (saya juga menggunakan ) dan tidak bisa me-mount file gambar DMG.
Saya pikir masalahnya dicatat di sini:
Kesalahan 30 sarana (lihat
man 2 intro
):Tidak mengherankan di sini, itu memang sistem file read-only, tapi ... ketika dipasang di AFP berfungsi, mengapa?
Karena implementasi Apple NFS memiliki beberapa masalah dengan penguncian. Sebagaimana dinyatakan dalam posting ini di gluster.org:
Dalam pengaturan saya, server NFS (yaitu, FreeNAS VM) tiba-tiba tidak responsif (dari Mac saya
/var/log/system.log
):Output dari
sudo /usr/bin/hdiutil attach -debug /Volumes/netboot/p7zip-9.04-0.i386.dmg -notremovable -shadow /private/var/netboot/Library-Shadow -owners on -noverify -noautofsck -nobrowse
itu:Kesalahan 5 berarti (lagi dari
man 2 intro
):yang tidak mengejutkan sama sekali, sistem file NFS hilang.
Penanganan masalah
Solusi (diuji pada OS X 10.8) adalah untuk memasang NFS dengan opsi
nolocks,locallocks
. Sebagaimana dijelaskan dalam posting di gluster.org yang telah disebutkan:Saya terpasang secara manual
172.16.54.186:/mnt/raid/netboot
dan bekerja dengan sempurna:Saya juga mengedit
/etc/auto_master
seperti ini:berhenti dan mulai
automountd
danautofsd
:dan bekerja seperti pesona:
sumber
nolocks,locallocks
membantu kinerja NFS dari share NFS read-only lainnya dengan file DMG, jadi terima kasih!/Library
gambar NetBoot kami di array RAID. Kami tidak lagi memerlukan ini karena kami membeli server Mac Pro baru)hdiutil melampirkan -bahkan hanya ...
Untuk gambar yang disimpan pada sistem file read-only, saya rasa itu
-readonly
harus digunakan pada saat lampiran.(Kasus AFP mungkin luar biasa.)
Mempertimbangkan suara turun dan komentar dari @Josh: Saya salah mengerti
-shadow
bagian dari halaman manual untukhdiutil
:- Saya membayangkan itu
-shadow
bisa menimpa-readonly
.sumber
-readonly
dan-shadow
akan membaca dari file shadow tapi mount image read-only. Jadi misalnya itu akan memungkinkan Anda untuk membaca perubahan yang dibuat ke file bayangan tanpa memperbarui file bayangan itu. Masalahnya adalah kunci NFS ketika jaume ditemukan.
