मैंने अपने Centos 7 में ZFS (0.6.5) स्थापित किया है और मैंने एक ज़ूलप भी बनाया है, सब कुछ इस तथ्य से अलग काम करता है कि मेरे डेटासेट रिबूट पर गायब हो जाते हैं।
मैं विभिन्न ऑनलाइन संसाधनों और ब्लॉगों की मदद से इस मुद्दे पर बहस करने की कोशिश कर रहा हूं लेकिन वांछित परिणाम नहीं मिल सका।
रिबूट के बाद, जब मैं zfs listकमांड जारी करता हूं तो मुझे "कोई डेटासेट उपलब्ध नहीं होता है" , और "कोई पूल उपलब्ध नहींzpool list है " देता है ,
बहुत सारे ऑनलाइन शोध करने के बाद, मैं इसे मैन्युअल रूप से कैश फ़ाइल आयात करके ज़ूल आयात -c कैशफाइल का उपयोग करके बना सकता हूं , लेकिन फिर भी मुझे रिबूट से पहले zump set cachefile = / etc / zfs / zpool.cache पूल चलाना था ताकि रिबूट के बाद इसे आयात किया जा सके।
यह क्या हैsystemctl status zfs-import-cache की तरह लगता है,

मुझे यकीन नहीं है कि यह एक ज्ञात मुद्दा है, अगर हां, तो क्या इसके लिए कोई वर्कअराउंड है? शायद रिबूट के बाद अपने डेटासेट को संरक्षित करने का एक आसान तरीका और अधिमानतः कैश फ़ाइल के ओवरहेड के बिना।
